E ranks fifth among final letters at fifteen letters, behind S, Y, N and G. U, C and P open the most words, at 36, 35 and 30, while -IVE covers 50 entries and -ABLE, -ATE and -INE add 43, 43 and 24. Only interchangeable counts as everyday English.

Fifteen-letter E endings at a glance

312 fifteen-letter words end in E.
E is the fifth-commonest final letter at this length.
-IVE covers 50 words, -ABLE and -ATE 43 each.
U opens 36, C 35 and P 30.
Only 1 entry counts as everyday English.
Oxyphenbutazone leads the scores at 41.

The scores run high for a silent final E

A final E usually means a quiet ending, but this group breaks that habit: oxyphenbutazone reaches 41, schizoaffective 40, and hydroxybutyrate and cyclohexylamine 37 each.

Rare tiles do the work. Oxyphenbutazone carries X, Y and Z, while schizoaffective pairs its Z with a V, and the long suffixes add almost nothing to either total.

Collins carries 286 of the 312 and NWL2023 182, so 130 entries are missing from North American games.

The same pattern holds lower down: apophthegmatize scores 37, comprehensivize 36 and photosynthesize 35, each a run of common letters with one rare tile attached.

Suffix length buys almost nothing. A six-letter -ABILITY tail scores the same as the two letters at its end, which is why the -IVE, -ABLE and -ATE groups stay mid-table.

-IVE, -ABLE and -ATE carry the endings

-IVE closes 50 words, including anticompetitive and uncommunicative.
-ABLE closes 43, from interchangeable to unpronounceable.
-ATE closes another 43, among them hydroxybutyrate.
-INE adds 24, such as pseudoephedrine.
-ENCE and -ANCE close 22 and 3.

One everyday word out of 312

Note

Interchangeable is the only entry here in common English. The rest are chemical, medical and technical terms, and 243 of the 312 do carry a dictionary definition, so a specialised vocabulary counts for more than a general one.

Questions people ask

How many 15-letter words end in E?

There are 312, and 286 of them sit in Collins against 182 in NWL2023. The -IVE suffix covers 50 entries, -ABLE and -ATE 43 each, and -INE another 24.

Which 15-letter word ending in E scores highest?

Oxyphenbutazone leads at 41 points. Schizoaffective follows at 40, then hydroxybutyrate and cyclohexylamine on 37, and every one of those leans on X, Y or Z.

Are any 15-letter E-ending words in everyday use?

Just one: interchangeable. The other 311 words are scientific, medical or technical vocabulary, and 243 of the 312 still carry a dictionary definition, so the list rewards a technical reader.
