Which words fit this letter frame?
Several entries grow from the same INF- stem: INFANTS, INFANCY, INFANTE and INFANTA; another cluster includes INFUSED, INFUSES and INFUSER. A separate INFIX pair gives INFIXED and INFIXES, the two top scorers, with INFEOFF next at 16. Grouping by the first four letters helps distinguish these families.
How can you narrow the remaining tiles?
Fifteen words end in S, more than any other final letter; T appears seven times and E five. The distribution makes plural-looking forms frequent, but do not assume every S ending marks a plural. For a board play, INFIXED scores 18 and INFIXES 17 before premium squares; the uncommon forms are poorer guesses when your game uses a narrower vocabulary.
Six of the 39 entries fall in the common-word group, so this is a mixed list rather than a uniformly obscure corner. Familiar choices such as INFANTS and INFUSED should be checked against the clue’s exact ending; the score-leading INFIXED family is a separate branch. E ends five of the 39, as INFLATE does.
If your final tile is known, use that distribution to prioritize likely candidates, then verify the inner letters rather than treating an ending as proof.
A practical clue check
Keep the third tile visible while sorting: INF- dominates the familiar set, but IFFIEST is also in the pattern and starts with a doubled F.
