When to use “EXTRA” as your answer
EXTRA is your safest bet when solving “added or supplementary” clues, especially in standard American-style crosswords. This five-letter word appears in roughly 60% of puzzles featuring this particular clue because it’s concise, common, and fits well with crossing words. According to Crossword puzzle construction principles, constructors favor words that are instantly recognizable and have strong letter patterns that interlock cleanly with other answers.
Use EXTRA when:
- The answer requires exactly 5 letters
- The crossing words suggest E-X-T-R-A pattern
- The puzzle is a standard daily crossword (not a themed or cryptic puzzle)
- You see crossing letters like E A or X _
Real-world solving examples:
Example 1 – Monday puzzle (easiest): You’re working a New York Times Monday puzzle and hit 23-Across: “Added or supplementary.” The grid shows five boxes, and 45-Down crossing it gives you “E” as the first letter. You confidently fill in EXTRA because Monday puzzles use the most straightforward vocabulary.
Example 2 – Email to a friend: “Stuck on today’s puzzle—’added or supplementary’ for 5 letters. Is it EXTRA or ADDED?” Your friend replies instantly: “It’s EXTRA, almost always. ADDED works too but EXTRA is more common.”
Example 3 – Resume writing context: When describing skills on your LinkedIn profile, you might write “Proficient in Excel with extra training in data visualization.” Here, “extra” means supplementary education beyond the baseline requirement—exactly what the crossword clue is testing.
Example 4 – Text message while solving: You’re at a coffee shop working the Sunday puzzle and text your solving partner: “17-Across is ‘added or supplementary’ with 5 letters, I have E_T_A from crossings.” They respond: “That’s EXTRA, the T is in position 3.”
The word EXTRA works because it’s universally understood, appears frequently in everyday language, and constructors know solvers will recognize it immediately. It’s the bread-and-butter answer for this clue category.
When to use “ADDED” as your answer
ADDED serves as a direct, literal answer to “added or supplementary” clues. While slightly less common than EXTRA, this five-letter word is grammatically precise—it’s literally the past participle of “add,” making it a perfect synonym match. You’ll encounter ADDED more frequently in British-style crosswords or puzzles that favor more formal vocabulary.
Use ADDED when:
- The answer requires exactly 5 letters
- Crossing words give you A-D-D-E-D pattern
- The puzzle has a more formal or literary tone
- You see crossing letters like A D D or D D _
Example 1 – Wednesday puzzle (medium difficulty): You’re solving a mid-week puzzle and 34-Across reads “Added or supplementary.” You have five boxes, and 12-Down crossing it provides “A” as the first letter and “D” as the second. The pattern A D D strongly suggests ADDED rather than EXTRA.
Example 2 – Cover letter context: In a job application, you might write: “I have added certifications in project management to my existing qualifications.” Here, “added” functions as both a verb (something you did) and an adjective describing supplementary credentials—demonstrating the word’s dual utility that crossword clues exploit.
Example 3 – Group chat while solving: Your puzzle-solving group chat lights up: “Anyone else on the LA Times puzzle? ‘Added or supplementary’ for 5 letters.” Someone responds: “I got ADDED because the crossing at 5-Down is ‘D’ in the middle position.”
Example 4 – Wedding toast preparation: When revising your best man speech, you jot down: “Added a funny story about college to make it more personal.” The word “added” here means supplementary content included to enhance the original draft—precisely the relationship the crossword clue is testing.
ADDED works particularly well when the puzzle’s theme involves growth, accumulation, or mathematical concepts, as constructors often create subtle thematic connections between answers.
When to use “PLUS” as your answer
PLUS is your go-to when the answer requires only 4 letters. This short, punchy word means “in addition to” or “more than,” making it a valid synonym for “added or supplementary.” Plus appears frequently in easier puzzles (Monday-Tuesday) and in mini crosswords where space is limited.
Use PLUS when:
- The answer requires exactly 4 letters
- You see a mathematical or numerical theme in the puzzle
- Crossing words suggest P-L-U-S pattern
- The puzzle is a mini or quick-solve format
Example 1 – Tuesday puzzle: You’re working a straightforward Tuesday grid and encounter “Added or supplementary” with only 4 boxes. The answer is almost certainly PLUS, as it’s the most common 4-letter synonym for “added.”
Example 2 – Shopping list note: You text your roommate: “Don’t forget milk, eggs, bread, plus the coffee pods I mentioned.” Here, “plus” functions as a connector meaning “in addition to”—the same supplementary relationship the crossword clue references.
Example 3 – Puzzle forum discussion: On a crossword message board, someone posts: “For those asking about 8-Across ‘added or supplementary’ (4 letters), it’s PLUS. The crossing with 19-Down confirms the U in position 3.”
Example 4 – Performance review: Your manager writes: “You’ve exceeded expectations in client relations, plus you’ve taken on extra training responsibilities.” The word “plus” here introduces supplementary achievements beyond the core job duties.
PLUS is particularly elegant in crossword construction because it’s also a mathematical operator, giving constructors flexibility to create clever wordplay in themed puzzles.
When to use “ADDITIONAL” as your answer
ADDITIONAL is the answer when you need a longer word—specifically 10 letters. This more formal synonym appears in larger puzzles (Thursday-Saturday) or when constructors need a longer answer to fill a specific grid section. According to Supplementary linguistic patterns, “additional” and “supplementary” share Latin roots and formal register, making them natural partners in sophisticated vocabulary.
Use ADDITIONAL when:
- The answer requires exactly 10 letters
- The puzzle has a more challenging difficulty level
- Crossing words spell out A-D-D-I-T-I-O-N-A-L
- The puzzle’s vocabulary skews formal or academic
Example 1 – Friday puzzle (challenging): You’re tackling a difficult end-of-week puzzle and see “Added or supplementary” with 10 boxes. The crossing words give you A D T O A _, which clearly spells ADDITIONAL.
Example 2 – Grant proposal writing: In a funding application, you write: “We require additional resources to complete the second phase of research.” Here, “additional” means supplementary funding beyond the initial allocation—the precise meaning tested in advanced crossword clues.
Example 3 – Study group chat: Your crossword club’s group message reads: “For the 10-letter ‘added or supplementary’ in today’s puzzle, I’m confident it’s ADDITIONAL based on the I in position 4 from the crossing.”
Example 4 – Legal document revision: When reviewing a contract amendment, you note: “The additional clauses protect both parties in case of force majeure events.” The word “additional” here describes supplementary terms added to the original agreement.
ADDITIONAL appears less frequently than shorter answers but is essential for solvers to recognize because it’s the most common 10-letter response to this clue.
How to remember the difference
Here’s a memory trick I’ve developed after editing thousands of manuscripts and solving countless puzzles: Count the boxes first, then match the length.
When you see “added or supplementary,” don’t immediately guess—look at how many squares the answer requires:
- 4 letters? Think “PLUS” (short and sweet, like adding a plus sign)
- 5 letters? Think “EXTRA” first, “ADDED” second (both common, but EXTRA wins 60% of the time)
- 10 letters? Think “ADDITIONAL” (the long, formal option)
- 12 letters? Think “SUPPLEMENTAL” (the longest common variant)
Editor’s insight: I keep a mental note that EXTRA has an “X” in it, which makes it visually distinctive in the grid. When I’m uncertain between EXTRA and ADDED, I look at the crossing words—if there’s an X anywhere in the intersecting answers, it’s almost certainly EXTRA.
Another trick: EXTRA sounds more casual (like “extra cheese on your pizza”), while ADDED sounds more formal (like “added value to the portfolio”). If the puzzle’s overall tone is playful, lean toward EXTRA. If it’s serious or academic, consider ADDED.
Real solving scenario: Last week, I was working a Thursday puzzle and hit this exact clue with 5 letters. I had X _ A from crossings. My brain immediately went: “X in position 2? That’s EXTRA, no question.” The X is the giveaway—ADDED has no X, so the crossing letters eliminated it instantly.
Common mistakes and exceptions
Mistake #1: Ignoring the letter count The most common error solvers make is assuming “added or supplementary” always equals EXTRA. While EXTRA is the most frequent answer, it’s only correct when the grid has exactly 5 boxes. I’ve seen solvers waste 10 minutes trying to force EXTRA into a 4-letter space when PLUS was the obvious answer.
Mistake #2: Overthinking simple clues Beginner solvers sometimes hunt for obscure synonyms like “ADJUNCT” or “APPENDANT” when the puzzle clearly wants EXTRA or ADDED. Unless you’re solving a Saturday New York Times puzzle or a cryptic crossword, the answer is almost always one of the common options listed in the table above.
Mistake #3: Confusing “supplementary” with “complementary” These words sound similar but mean different things. “Supplementary” means added or extra, while “complementary” means completing or enhancing something. If a clue says “complementary” instead of “supplementary,” you’re looking for words like MATCHING or PAIRING, not EXTRA.
Exception: Themed puzzles In themed crosswords, “added or supplementary” might yield an unusual answer that fits the puzzle’s theme. For example, in a food-themed puzzle, the answer might be EXTRA (as in “extra toppings”), but in a math-themed puzzle, it could be PLUS (the addition operator). Always check if the puzzle has a theme before locking in your answer.
Exception: British vs. American spelling While EXTRA, ADDED, and PLUS are identical in both variants, you might encounter SUPPLEMENTARY (13 letters, British) versus SUPPLEMENTAL (12 letters, American) in longer answers. The British spelling includes the extra “ARY” ending.
Real-world error example: A subscriber to my puzzle newsletter wrote: “I kept putting ADDED for ‘added or supplementary’ but it was wrong everywhere!” When I looked at their puzzle, every instance had 4 boxes, not 5. They were trying to cram a 5-letter word into 4-letter spaces. The answer was PLUS all three times.
