Why?

• "Discovering a crossword's theme is... often half the fun of solving. And once you nail one answer
  in a puzzle's theme, figuring out the other long answers is usually much easier." ~Will Shortz
• "Crosswords, like any art,... should reflect life." ~Will Shortz
• Themes are often playful, and add another layer of depth to solve: a puzzle within a puzzle
• With consistent theme entries, figuring out one or two can help the solver solve the other theme entries.

Theme Types

• Wikipedia: "Many American crossword puzzles contain a 'theme' consisting of a number
  of long entries (generally 3-5 in a standard 15x15-square 'weekday'-size puzzle)
  that share some relationship, type of pun, or other element in common.
• Examples:
• Category theme: theme elements are all members of the same set
• e.g., five themed entries ending in the different parts of a tree: (NYT 4/26/2005)
  SQUARE ROOT, TABLE LEAF, WARDROBE TRUNK, BRAIN STEM, BANK BRANCH
• Quote themes, featuring a famous quote broken up into parts
  to fit in the grid (and usually clued as 'Quote, part 1',...);
• Rebus themes, where multiple letters or even symbols
  occupy a single square in the puzzle (e.g., BERMUDA Δ);
• Addition themes, where theme entries are created by adding
  a letter, letters, or word(s) to an existing word or phrase.
• e.g., "Crucial pool shot?" = CRITICAL MASSE
  (formed by taking the phrase "critical mass" and adding an "e" on the end.
  All the theme entries in a given puzzle must be formed by the same process
  (so another entry might be "Greco-Roman buddy?" = WRESTLING MATE
  -- "wrestling mat" with an "e" added on). An example of a multiple-letter
  addition (and one that does not occur at the end of the entry) might be
  "Crazy about kitchen storage?" = CABINET FEVER (derived from "cabin fever");
• Subtraction themes, the reverse of the above,
  where letters are removed to make a new word or phrase;
• Compound themes, where the starts or ends of the
  theme entries can all precede or follow another word,
  which is given elsewhere in the puzzle.
• e.g., a puzzle with theme entries that begin with
  PAPER, BALL, and WATER and elsewhere in the puzzle,
  the word BOY clued as "Word that can follow the start of [theme entries]";
• Anniversary or tribute themes, commemorating a specific person, place, or event.
• e.g., the NYT 10/7/2011 crossword commemorated the life of
  Apple CEO Steve Jobs who had died on October 5. Theme entries related to Jobs' life included
  MACINTOSH, PIXAR, THINK DIFFERENT, CREATIVE GENIUS, STEVE JOBS, and APPLE.
• Synonym themes, where the theme entries all contain synonyms
• e.g., a Los Angeles Times puzzle featuring a set of theme entries that contain
  the words RAVEN, JET, EBONY, and SABLE, all synonyms for "black"
• Numerous other types have been identified, including spoonerisms, poems,
  shifted letters, rhyming phrases, puns, homophones, and
  combinations of two or more of other types of themes."

• "Meta" crosswords were around long before FaceBook discovered and co-opted the term.
• "Crossword metapuzzles are crosswords that, when correctly solved,
  provide the basis for a second puzzle." ~ Wikipedia: Metapuzzle
• "Meta puzzles (also sometimes called contest puzzles) are crossword puzzles with an extra challenge.
  First, the grid is filled out like any other crossword puzzle.
  Afterwards, there is a prompt asking the solver for the solution to the meta.
  The prompt might ask for a 5-letter word, or for a word in a specific category, or anything else!
  To figure out the solution the solver needs to look for hints in the puzzle's clues, entries, grid layout,
  title, or anywhere else a devious constructor might have hidden them." ~Crosshare
• See section: CROSSWORDS: Terminology & Types: meta

Process / Conventions

• “Do you come up with the clues or the answers first?
  When constructing a themed crossword, puzzle makers usually tackle the theme itself first.
  They usually have a handful of “theme entries” with clues in mind, and they place those entries
  in an empty grid. The constructor then strategically places the black squares. Most constructors
  these days use software and curated word lists to help them fill the rest of the grid.
  
  For a themeless puzzle, like those we publish on Fridays and Saturdays, constructors start
  with an empty canvas. There are many methods for constructing this type of puzzle;
  some people already have a punny clue in mind for an entry and want to feature that
  clue-and-answer pairing. Some puzzle makers begin with an empty grid with a design they
  particularly like and just take what comes. Others might start with a stack of entries that work
  well together because of vowel and consonant patterns and build the grid around an entire stack.
  
  Generally speaking, clues are the last step of the process except for the occasional clue
  that comes to mind while you’re filling a grid. When I’m constructing a themeless puzzle,
  I put some thought into how easy it will be to write a clue for an entry but typically don’t
  write down any clues until the grid is complete. The grid evolves quite a lot during the
  construction process, so many entries that start out in the grid are replaced in the end."
  ~Christina Iverson, Wordplay newsletter, 11/10/2023
• "How do you plan a crossword with a particular theme without getting lost in the fillers?
  When I first started solving crosswords, I was a little baffled by the idea of a theme.
  I felt like if there was a theme, all the words in the grid should pertain to it. I quickly
  realized how impossible this would be for a Times crossword. It’s hard enough to get around
  70 words to cross one another in a 15x15 grid, much less words that are all somehow related.
  
  When constructors make themed puzzles, they start by coming up with the theme set, usually
  four or five phrases that are connected. The theme answers are typically the longest Across
  entries and are placed symmetrically in the grid. That means they usually come in pairs,
  but sometimes there’s an unpaired entry in the center of the grid.
  
  These conventions of theme placement exist to help solvers more easily uncover the theme.
  Sometimes we have additional ways of drawing solvers' attention to theme clues, such as
  asterisks or italics. These are especially useful when the theme entries are on the
  shorter side, or when there are other long entries in the grid.
  
  Entries that aren't thematic are called the fill of the grid. When editors review puzzles
  and like a theme, we often say, 'Should we check the fill?' Most of the fill consists
  of relatively short entries, but we like to see fun longer Down entries. These long,
  nonthematic entries are sometimes referred to as bonus entries or bonus fill because
  they add a little more color and life to the puzzle. Because they run vertically,
  they’re less distracting to solvers than long answers that run parallel to theme entries.
  The theme of a well-made puzzle leaves the solver with an 'aha!' and not a 'Huh?'"
  ~Christina Iverson, Easy Mode newsletter, 4/19/2024
• Generate prioritized list of possible phrases/words
• How to find initial theme entry? Reading, noticing, listening, ...
• How to find other theme possibilities? How are they similar?
  e.g., match a pattern (?*) in online dictionaries, e.g.: XWordInfo.com/Finder, OneLook.com
• # theme entries: 4-5? total theme letters/squares: 40-50? -- for 15 x 15
• Why the LA Times Won't Accept Your Three-Entry Theme
  (and Why You Should Make the Puzzle Anyways) 8/11/2021
• Generally, theme entries are the longest entries, paired by length; minimum 40 letters total
• If the entries contain a natural sequence, editors might expect them to occur in that order from top to bottom.
• Draft initial clues to ensure consistency of the theme entries.
• Option: place additional (unmatched) odd-length theme entry in center?
• Option: use a 'payoff' or 'reveal' entry (often last, or sometimes center entry)
  -- and/or a title -- to explain/suggest the theme?

Guidelines

• Some publishers allow a query containing only theme entries and clues for (hopefully) early feedback;
  with encouragement, continue with your efforts for a full puzzle; with rejection, rework or discard theme.
• Check Crossword Publication Specs for guidance, e.g.
• NYT: "Themes should be fresh, interesting, narrowly defined and consistently applied throughout the puzzle.
  For example, if the theme includes a particular kind of pun, then all the puns should be of that kind.
  Themes and theme entries should be accessible to everyone.
  We generally prefer puzzles with playful themes rather than straightforward subjects."
• LAT: "consistent and narrowly defined; We do not have titles on our daily puzzles, so the themes
  must be self-evident or tied together with an in-grid entry that acts as a reveal to sum up the gimmick.
  Puzzles should have at least 40 theme squares; four or more theme entries is ideal,
  but three 15s may be acceptable."
• WSJ: "entertaining theme, tightly defined and consistently executed"
• Univ.: "All Universal Crossword themes should have some element of wordplay.
  Every theme should also have a reason for doing what it’s doing.
  This reason should be described by either a title, a revealer, or both.
  For a 15x15, longer theme answers are preferred, but 7 letters is the standard minimum length.
  For a 21x21, it’s preferable for some answers to be 16+-letters long.
  Most of our 15x15s have 4-5 theme answers, and most of our 21x21s have 6-9 theme answers.
  Puzzles with fewer theme answers should have longer ones.
  21x21 puzzles have to entertain solvers for longer,
  so a theme we like as a 15x15 may not be as exciting to us as a 21x21.
  More specifically, if the joke starts feeling stale after a few examples or only a few
  of the examples are really solid, then we’d probably prefer the theme as a daily.
  Themes should be executed consistently, and none of the theme answers should feel like outliers.
  
  Here are some examples of what we mean:
  Do not mix add-a-letter and change-a-letter theme answers (e.g., BRAIN SHOWER and MIND SWEEPER,
  where the former adds the letter “b” and the latter changes an “e” to a “d”).
  For a theme based on word pronunciations, be mindful of consistency of both sound and spelling.
  For example, if a theme adds the letters PI to each theme answer and hinges around words
  being pronounced like “pie,” there shouldn’t be any examples where the PI is pronounced like “pea.”
  For puzzles whose theme answers hide words or anagrams,
  we prefer when those words are 4+-letters long and span word breaks.
  For bookend themes, we also prefer when the words are 4+-letters long,
  and we also like it when the bookended words can only split in one way.
  Yes: AIRPLANE TICKET hides the long word “planet” across a word break.
  Yes: PHILOSOPHERS STONE has the word “phone” as a bookend.
  No: BRAINWASH hides the word “rain,” but it isn’t across a word break.
  No: START A WAR has the word “star” as a bookend, but “star” is also hidden straight in the answer
  STAND CLEAR has the word “star” as a bookend but “star” can be split in more ways than one.
  This is not always a dealbreaker, but it’s unideal.
  For themes where all theme answers start or end with a synonym for something,
  we want the synonyms to change meaning and be separate words within their theme answers.
  For example, if all the theme answers start with animals, we’d be more excited by the
  theme answer BEAR DOWN ON than we would about BEAR SPRAY.
  
  Themes types that are accepted sparingly:
  “Words that precede or follow X” puzzles (e.g. a puzzle with the reveal BEFOREHAND
  and theme answers like FIRST IMPRESSION and BACK TO THE FUTURE,
  where “first” and “back” can precede “hand” [firsthand and backhand]), unless there’s an additional twist
  Puzzles where every theme answer hides the same word
  List puzzles (e.g., a puzzle whose theme answers are all songs by a certain artist)
  Quote/quip puzzles where a quote is broken up across a handful of theme answers
  Trivia/tribute puzzles that lack an additional layer of wordplay
  Mashup puzzles (e.g., a puzzle with theme answers like BRAINWASHING MACHINE [brainwashing + washing machine])
  Add-a-single-letter/delete-a-single-letter puzzles, unless there’s an additional twist
  Puzzles whose theme answers are nonsensical (e.g., a puzzle with the reveal SKIP A BEAT
  and theme answers like RIX POTTER [where “beat” was deleted from Beatrix Potter])
  “Reverse clue” puzzles whose theme answers aren’t legitimate phrases
  (e.g., a puzzle with theme answers like INTERSECTION SIGN and ORGAN FEATURE, both clued as [Stop])
  Puzzles whose theme answers/clues are either hard to imagine or grammatically unsound.
  This usually applies to puns (e.g., BLUE OUT THE CANDLES, which doesn’t have a cogent cluing angle).
  Themes that scatter circles throughout theme answers (non-consecutive circled letters
  that aren’t bookends) usually aren’t a good fit for Universal"
• Cruciverb: Advice on Making 21 x 21 Puzzles
  Get theme approval from an editor before tackling a grid design or fill.
  21 x 21's are way too difficult to do on spec.
  Bare minimum: 80 theme squares (8 10-letter entries).
  If your entries are all very long (16-21), 5 entries may be enough.
  If most of your theme entries are shorter (say 9-12 letters)
  you want at least 8 entries--I often try for 9.
  When I have several pairs of entries that are 15 letters or longer,
  I sometimes settle for 7 entries or even 6.
  Avoid a single central entry of 17 or 19 letters

Is the Theme Unique -- or 'Fresh'?

• If you're planning to submit the crossword to a publisher,
  it's important early in the process to find out if the theme has already appeared elsewhere
  (this is not an issue when creating crosswords just for fun, friends or family).
• The 3 first examples NYT, LAT and WSJ all used a "PUZZLE PIECE" theme
  and even shared the same "reveal" entry or title,
  but the idea, entries and clues were different, i.e., "pieces" = music, articles, fragments.
• However, if the other entries are almost exactly the same or share the same theme idea,
  a publisher is likely to reject the submission as not fresh enough.
• With increasingly more crossword venues and imaginative constructors,
  it can be challenging to come up with new themes or interpretations of a theme.
• A later section revisits this issue, with other examples,
  and offers tips for identifying existing puzzle themes.

Is the Theme Fresh?

• As mentioned earlier, crossword editors prefer new themes.
  Unlike movie producers, they often reject remakes.
• You could provide different fill words and clues to avoid actual plagiarism, or consider submitting to a different publication,
  but you'll probably have a better chance with a different theme.
• There is no public puzzle database available to search, nor an index of theme 'ideas'.
  However, there are several places to check where (and usually when) entries have already appeared.
  If you have a reveal entry, is it used as a reveal entry elsewhere?
  Do several of your theme entries occur in the same existing puzzle?
