The starting tile narrows the search sharply: I begins 147 of these words, while E and A account for 52 and 49. Their endings cluster just as strongly, with S appearing 127 times. Familiar examples include IMPERFECTIONS and EMBARRASSMENT, but only 4 entries meet the common-word frequency threshold, so expect plenty of specialist vocabulary.

Quick counts for the M-second pattern

The combined tournament-dictionary count is 266 words.
I is the leading first letter, with 147 matches.
S is the most common final letter, occurring in 127 matches.
Only 4 words meet the common-word frequency cutoff.
EMBEZZLEMENTS scores 37 points, the highest score in the examples.

Which opening letters occur most?

IM- words dominate: IMPOSSIBILITY, IMPERCEPTIBLE, and IMPROVISATION all start with I and place M next. The 147 I-openers outnumber the 52 E-openers by nearly three to one.

A is close behind E, with 49 matches such as AMPLIFICATION and AMBASSADORIAL. O contributes 11 words; S and U are much rarer, with 4 and 3 respectively. The first tile is a strong sorting clue, especially when I, E, or A is already known.

How to use 13-letter words with M as the 2nd letter

When the final tile is known, start with S: 127 words end there. Y is the next most frequent ending at 44, followed by E at 25. IMPERFECTIONS and IMPRESSIONISM show how an IM opening and an S ending can narrow a search.

Dictionary coverage varies: Collins includes 260 matches, NWL2023 includes 178, and ENABLE includes 161. These counts overlap rather than forming separate pools. With only 4 common entries, obscure vocabulary is a real limitation; check your game's word list before playing an unfamiliar answer.

Questions people ask

How large is the group of 13-letter words with M second?

The group contains 266 words accepted by at least one of the covered tournament dictionaries. I starts 147 of them, making it the clearest first-letter clue; E and A follow with 52 and 49 matches.

Which M-second word has the highest Scrabble score?

EMBEZZLEMENTS leads the scoring examples at 37 points. EMPYREUMATIZE reaches 31, while IMMUNOCOMPLEX scores 30. A game's dictionary still determines whether any particular word can be played.

Are most of these 13-letter words common?

No. Just 4 of the 266 entries fall within the common-word frequency threshold. IMPROVISATION and IMPERFECTIONS are recognizable examples, but many matches belong to less familiar or specialized vocabulary.
