6-letter words with M as the 2nd letter and S as the 5th letter

Lock in the pattern _M__S_ and the options narrow quickly: just 23 tournament-listed words fit. IMPOSE and AMIDST stand out as recognizable examples, while EMBOSK and IMMASK are better known for their tile value. Only 3 matches rank among the commonest English words, so expect an unusual choice if the familiar options are already ruled out.

At a glance: the M-and-S pattern

• The pattern _M__S_ has 23 six-letter matches in tournament dictionaries.
• IMPOSE and AMIDST are familiar examples; AMBUSH also fits the fixed positions.
• Only 3 matches count as common by the frequency measure.
• EMBOSK, IMBOSK, and IMMASK tie for the highest score at 14 points.

How do these six-letter words begin?

E leads 10 matches and I leads 8, so those two starting letters account for 18 of the 23 options. S begins 3, while A begins 2. When the pattern is fixed, checking E and I first covers most of the list.

Dictionary coverage varies: Collins contains 22 matches, NWL2023 contains 11, and ENABLE contains 8. Those totals overlap, so they do not add up to 23; each word is counted once if it appears in at least one of the three lists.

The M-and-S pattern is especially selective beside nearby second-letter choices. With A in the second position, the same final constraint has 113 matches; E has 91. The 23 M words make a much shorter search.

Which matches score highest?

EMBOSK, IMBOSK, and IMMASK each score 14 points before board bonuses. AMBUSH, IMPISH, and EMBUSY follow at 13, while the set averages 11 points. The top scores come from less familiar words, not the everyday choices.

IMPOSE and AMIDST are easier to recognize, but only 3 of the 23 matches are classed as common. Treat the pattern as a clue filter rather than a promise of a familiar answer; most remaining choices are niche.
