7-letter words with M as the 3rd letter and S as the 5th letter

The fixed pattern is _ _ M _ S _ _, which narrows the search to a compact set rather than a general seven-letter list. Familiar entries include NEMESIS, OSMOSIS, NAMASTE, and BEMUSED, but just one match ranks among the top 25,000 English words by frequency. Most remaining choices are specialist or inflected forms, so a recognizable shape does not guarantee acceptance in every game dictionary.

7-letter words with M as the 3rd letter and S as the 5th letter

• Exactly 60 tournament-dictionary words fit the M _ _ S _ _ pattern.
• Collins accepts 58; NWL2023 accepts 51, so the full set differs by game.
• Only one match ranks among the top 25,000 English words by frequency.
• Forty-three matches end in S, including familiar plurals and verb forms.
• ZYMOSAN, ZYMOSIS, ZYMASES, and ZYMOSES score 21 apiece.

Which endings and word families should you check?

More than two-thirds of the matches finish in S: 43 of the 60. That ending is not a second clue to overlook; it often marks plurals or verb forms, as in MIMOSAS, SAMOSAS, UNMASKS, and DEMISES. Opening letters are more spread out: D leads with eight words, C has seven, and M has six.

A known final S narrows the search more sharply than a guessed first letter.

Several entries form recognizable families. NEMESIS pairs with NEMESES, OSMOSIS with OSMOSES, and DEMISED with DEMISES; those parallels can turn a partial pattern into a quick check. NAMASTE and TAMASHA take a different route: their required M and S sit inside words that do not end in S.

Final S dominates, but it is not required.

Which matches score well, and where are they accepted?

ZYMOSAN, ZYMOSIS, ZYMASES, and ZYMOSES each score 21 in Scrabble, the highest value among these matches. Their shared ZY opening carries the scoring weight, so recognizing that cluster is more efficient than memorizing four unrelated words. JAMESES scores 16, while DAMASKS scores 14; a less familiar spelling can beat an everyday-looking option.

Dictionary coverage is a real limitation: the 60-word total includes entries from at least one tournament list, not every game list. Collins includes 58 matches, compared with 51 in NWL2023 and 44 in ENABLE; only 48 have definitions available. Check your game's word list before playing an obscure form, especially when a rack depends on one narrow spelling.
