7-letter words with M as the 3rd letter and S as the 4th letter

The fixed pattern is __MS___: M and S sit side by side in the middle, while the first, second, fifth, sixth, and final letters remain open. Only two entries rank among common English words, so recognizable HIMSELF and HAMSTER stand out from a largely specialist set. The dictionary split also matters: Collins includes 29 matches, compared with 26 in NWL2023 and 20 in ENABLE.

7-letter words with M third and S fourth

• Exactly 32 tournament-dictionary words fit the __MS___ pattern.
• Only two matches are common by our frequency measure.
• Collins recognizes 29; NWL2023 recognizes 26; ENABLE recognizes 20.
• ZEMSTVO and ZEMSTVA lead the scoring at 21 points each.
• Ten matches end in S, the most frequent final letter.

Which matching words score the most?

ZEMSTVO and ZEMSTVA each score 21 points before board premiums, putting them at the top of this group. COMSYMP follows at 18, then CUMSHAW at 17; GEMSBOK and JIMSONS each reach 16. The useful pattern is the unusual letter cluster, not the opening: the two Z words share the same M-S core and differ only at the end.

Those points come with a vocabulary catch. ZEMSTVO, COMSYMP, CUMSHAW, and GEMSBOK are less familiar than HIMSELF, and only 26 of the 32 matches are marked defined. Check the word list used in your game before building a rack around a specialist entry; dictionary acceptance varies, with ENABLE supporting 20 and Collins 29.

Use the ending to narrow the pattern

S closes 10 matches, while R closes four and N closes three. Examples include DAMSELS and JIMSONS for final S, HAMSTER for final R, and HIMSELF for final F. That makes the ending a stronger filter than guessing the first letter, especially when a puzzle has already fixed the middle pair.

M and S each start four matches; A, C, G, and R each start three. The neighboring pattern with S in both middle slots has 271 matches, far more than this pattern's 32. Keep M-S fixed, then use the ending to narrow candidates; changing the third letter to S opens that larger pattern.
