The answer to the NYT crossword clue “Ultimate function” is END USE. Six letters. Two words. And one of the cleaner misdirects the Friday puzzle pulled off in August 2025.
If the answer surprised you, that is the point. Here is exactly why it works — and what to do when you hit a clue structured the same way.

| Ultimate function | END USE | 6 | August 22, 2025 (Friday) |
Why the Clue Points to END USE
The logic is a two-part synonym substitution, which is a standard Friday NYT crossword technique:
- “Ultimate” maps to END — meaning final or last, not greatest or extreme
- “Function” maps to USE — meaning purpose or application
That is the whole equation. The clue steers solvers toward “ultimate” as a superlative — something along the lines of “the greatest purpose” — when the actual reading is purely positional. Final purpose. End use.
Will Shortz and constructor Gia Bosko built it to create exactly that hesitation. On a Friday grid, a clue that reads naturally in one direction while meaning something more literal is standard operating procedure.
What “End Use” Actually Means
End use is a real, widely used term. It refers to the final, intended purpose for which a product, material, or technology is designed or deployed.
You will find it across several fields:
- Export control law — governments require end-use certificates before authorizing transfers of sensitive technology or equipment
- Semiconductor trade regulations — export restrictions on advanced chips specify approved end uses
- Manufacturing and procurement — contracts frequently define end use to set acceptable applications and limit liability
- Product safety standards — determining a product’s intended end use affects which safety requirements apply
It is not a phrase that comes up in casual conversation, which is precisely why it functions well as a crossword answer. Solvers have to think past the obvious synonyms and land somewhere more specific.
The August 22, 2025 Puzzle
The clue appeared in the Friday, August 22, 2025 NYT crossword, constructed by Gia Bosko. It was her fifth puzzle published in The New York Times.
Friday puzzles are themeless, meaning no hidden concept ties the answers together. The difficulty comes entirely from the cluing. This grid stood out — its flow score ranked at the 98th percentile of all Modern Era NYT crosswords according to XWord Info, the definitive crossword archive.
Other Notable Answers in the Same Grid
The puzzle carried several long, grid-spanning entries that reviewers at Crossword Fiend rated the overall puzzle four out of five stars:
| Answer | Length |
|---|---|
| REVERSE ENGINEER | 15 letters |
| FAIRY TALE ENDING | 15 letters |
| RAISE THE CURTAIN | 15 letters |
| TAKE NO PRISONERS | 15 letters |
Additional answers that drew attention included BINGO PARLOR, SAMUEL CHASE (the only U.S. Supreme Court justice ever impeached, acquitted by the Senate in 1804), and OSTENTATION — clued as the collective noun for a group of peacocks.
How the NYT Crossword Difficulty Scale Works
Understanding where Friday sits in the weekly schedule helps explain why END USE works as a clue answer at all. On a Monday, the same concept would likely be clued as something far more direct.
| Day | Difficulty |
|---|---|
| Monday | Easiest |
| Tuesday | Easy |
| Wednesday | Medium |
| Thursday | Tricky, often theme-based |
| Friday | Hard, themeless |
| Saturday | Hardest, themeless |
| Sunday | Medium-hard, larger 21×21 grid |
Friday and Saturday clues routinely rely on indirect word associations, secondary definitions, and misdirection. A clue that reads like a philosophical statement is often just a two-word synonym swap at its core.
Solving Friday Clues Structured Like This One
When a Friday or Saturday NYT clue trips you up, this approach works:
- Break the clue into individual words — each word often maps to a separate component of the answer
- Try the most literal synonyms first — “ultimate” as final before greatest, “function” as use before role or purpose
- Look for compound answers — NYT answers frequently combine two short common words rather than offering one long synonym
- Use letter count and crossing letters — even one confirmed cross can make the rest visible
- Watch adjectives closely — words like “ultimate,” “final,” and “prime” are common misdirects that map to positional words like end, last, or top
The NYT crossword has been published daily since February 15, 1942. In that time, the Friday slot has stayed reliably consistent in what it demands from solvers: less general knowledge, more lateral thinking. The “ultimate function” crossword clue is a clean example of that — a phrase that looks abstract but resolves to two of the most common words in the English language, just not the two most solvers reach for first.
