5 Letter Words With F and K
Every five-letter word that contains both F and K, in any position — answer-eligible words flagged in green, tap any word to play.
How Many 5-Letter Words Have F and K?
Only 38 five-letter words carry both F and K, which makes this one of the tighter pairs on the board — narrower than about 83% of all letter pairings. The answer pool trims it further, to 17: FLACK, FLAKE, FLAKY and the rest. A list this short is one you read rather than guess at.
There is a mild lean but no rule. F shows up most in the 1st slot (39%) and K in the 1st (42%); FLACK, FLAKE, FLAKY match the first pattern. Use it as a tiebreaker, not a plan.
Adjacency is close to a dead end here: 2 of 38 words run F and K together, namely NAKFA, WAKFS. Plan for at least one square between them.
Green-dotted words are answer-eligible — the everyday vocabulary the daily puzzle actually draws from — while hollow-dotted words are valid guesses you can play but that will never be the solution. Flip on Answers only to focus on the 17 words that can truly win the board.

F/K Words That Have Been Wordle Answers

Never used as an answer
3 answer-eligible F/K words have never been the solution: FLACK, FLECK, FRISK . Wordle avoided repeats entirely for its first 1,688 puzzles and only began reusing old answers in February 2026 — 24 times so far. An unused word is still the likelier bet, just no longer a certainty; see how repeats work for the full picture.
The other 21 words on this list are valid guesses the game accepts but never chooses as a solution. They still make useful probes for placing F and K, but when you guess to win, a green-dotted answer word is the smarter pick.
Where F and K Land in 5-Letter Words
The whole puzzle now is placement, so here is exactly where each letter tends to sit across the 38 words. Try the busiest square first.
| Position | Words with F here | Words with K here |
|---|---|---|
| 1st | 15 | 16 |
| 2nd | 0 | 5 |
| 3rd | 5 | 2 |
| 4th | 14 | 4 |
| 5th | 7 | 11 |
Play a candidate that seats each letter in its busiest square and one of two good things happens: a tile turns green and you have locked a position, or it turns yellow again and you have eliminated the single most likely slot in one move.
How to Use These Words to Win Wordle
- Lead with the busiest square. F in slot 1 covers 15 of these 38 words and K in slot 1 covers 16 — try that shape before rarer placements.
- Favor distinct letters early. 30 of the 38 words here use five different letters and 8 repeat one.
- Lean toward an unused word. Repeats stayed at zero until February 2026 and number just 24 in 1916 puzzles, so the 3 never-used F/K words above remain the stronger bet.
Full strategy lives in the how-to-play guide, and you can practice any time on the unlimited Wordle board.
