6-letter words with M as the 3rd letter and U as the 4th letter

The fixed middle pair leaves room for very different endings: nine words finish in E, nine in S, and eight in I. IMMUNE and DEMURE are familiar choices, but most entries are uncommon; just one falls within the top 25,000 English words by frequency. Dictionary coverage also varies, so a match in one word list may not appear in another.

At a glance: 6-letter words with M third and U fourth

• The pattern has 34 matches across the tournament dictionaries.
• Only one of the 34 is among the top 25,000 English words by frequency.
• IMMUNE and DEMURE are recognizable examples with the required middle letters.
• SHMUCK is the top scorer at 17 points.
• Collins includes 33 matches, compared with 27 in NWL2023 and 25 in ENABLE.

Which endings appear most often?

E and S tie as the leading final letters, with nine matches each. IMMUNE and DEMURE show the E ending; LEMURS and FEMURS illustrate S. The next most common ending is I, found on eight words, including TUMULI and FAMULI.

That distribution gives you a practical way to narrow a clue: an E, S, or I at the end accounts for 26 of the 34 matches. The remaining endings are G, A, D, K, and O, with two words ending in G and one apiece ending in the other four letters.

How should you use this pattern in a word game?

Start with the ending if your puzzle reveals one: E, S, and I cover most of the matches. Then test a familiar candidate such as IMMUNE, DEMURE, or BEMUSE before reaching for rarer vocabulary. SHMUCK is the standout scoring play, but its unusual opening makes it a less natural everyday guess.

The main limitation is familiarity: only one match is common by the frequency measure, and several examples, including OSMUND and SIMURG, are specialized. Check your game's word list before committing to a less familiar option. This pattern is specifically 6-letter words with M third and U fourth, not every word containing the pair MU.
