Only 13 tournament-dictionary words fit this six-letter pattern, and each ends in I. NUCLEI and SENSEI are the recognizable examples; CLYPEI tops the scoring list. Just two entries meet the common-word frequency cutoff, so expect specialist vocabulary alongside familiar words.

How many 6-letter words have E fifth and I sixth?

  • The complete set contains 13 words, all with E fifth and I sixth.
  • S is the most frequent first letter: four matches begin there.
  • A, N and P each start two words; C, G and M each start one.
  • CLYPEI scores 13, ahead of ARCHEI at 11 and SAIKEI at 10.
  • Collins lists 13 matches, versus 9 in NWL2023 and 8 in ENABLE.

How do the starting letters divide these matches?

The final I is fixed across all 13 results, so it cannot distinguish candidates once the pattern is known. Use the initial letter instead: S accounts for four entries, the largest starting group, while A, N and P contribute two each.

That makes S a sensible first branch when searching from an incomplete rack, but it does not make an S-word certain. The remaining single-start entries begin C, G or M. Once the initial tile is settled, compare the middle letters against the actual candidate words rather than treating the shared ending as a clue.

For a rack search, pin the final I and fifth-position E first, then split the remaining checks by starting letter. Testing I again adds no information because every match already ends with it.

Which entries are familiar, and which score?

NUCLEI and SENSEI are the easiest examples to recognize, but only two of the 13 match the common-word cutoff. Other entries include MALLEI and GLUTEI, plus less familiar forms such as CLYPEI and SIFREI. A familiar-looking ending does not make every whole word familiar.

Dictionary coverage changes with the game: Collins has all 13, NWL2023 includes 9, and ENABLE includes 8. Those totals show why an entry accepted in one setting may fail another. Check the word list used in your game before playing an unfamiliar form.
