About 6-letter words ending in UM

Every word here is exactly 6 letters with um locked into the final slot. Ranked 44 of 111, "um" is a middling ending at this length: common enough to be worth guessing, rare enough that the list stays readable.

Two-letter endings do most of the grammatical work in English. Plurals, past tenses, comparatives and agent nouns all crowd onto a handful of final pairs, which is why some endings return hundreds of words and others barely clear the cutoff. Inside this set, the letter sitting immediately next to the fixed pair is most often I (38), T (15), L (13).

People search this one both ways round, as six letter words ending in um and as um words 6 letters. Both mean the same thing, and this is the list. If the length is wrong, the sibling lengths are below.

Quick answers

How many 6-letter words ending in um are there?

121 of them, out of 22,418 six-letter words, or about 0.5% of the length. Ranked 44 of 111, "um" is a middling ending at this length: common enough to be worth guessing, rare enough that the list stays readable.

Why does this page only cover 6-letter words?

Because a length and an ending together are what you usually know. If you need a different size, the list below moves "um" to the other lengths that have enough words to be worth a page. Dropping the length entirely gives you every word ending in M instead.

What usually comes next in these words?

The letter just inside the fixed pair is most often I (38), T (15), L (13). Two-letter endings do most of the grammatical work in English. Plurals, past tenses, comparatives and agent nouns all crowd onto a handful of final pairs, which is why some endings return hundreds of words and others barely clear the cutoff.

Do you have a page for every two-letter ending?

No, and deliberately so. A pair only gets a page when at least 35 six-letter words share it. Below that the list is too short to be worth a visit, so we send you to the single-letter list instead.

Are proper nouns or abbreviations included?

No. Only standard dictionary words appear, which matches what Wordle, Scrabble, and crossword grids accept. A missing word is almost always a name, a hyphenation, or an abbreviation.
