14-letter words with X as the 2nd letter

This pattern is strikingly lopsided: 84 of the 92 entries start with E, while O, A, and U account for the rest. The list includes long scientific and technical terms alongside familiar word forms. None ranks among the top 25,000 English words by frequency, so treat these as puzzle and word-game candidates rather than everyday vocabulary.

At a glance: 14-letter words with X as the second letter

• The pattern contains 92 words accepted by at least one tournament dictionary.
• E begins 84 entries; O begins 4, A begins 3, and U begins 1.
• Forty entries end in S, and 20 end in Y.
• Collins lists 88 entries, compared with 69 in NWL2023 and 63 in ENABLE.
• The neighbouring 15-letter X-second list is smaller, with 83 entries.

Why do so many entries begin with E?

The dominant shape is EX: experimentally, excommunicated, exceptionalism, and existentialism all put X in the second position. The 84 E-starting words make this pattern a useful clue when you already know the opening letters, but the long forms are mostly specialized vocabulary.

Not every entry follows the EX pattern. Oxidoreductase starts with OX, while axiomatization starts with AX; together, these examples show why a fixed second-letter clue should not be mistaken for a fixed prefix. The first-letter counts leave only five words outside the E and O groups: three begin with A and one with U, alongside O's four.

Endings narrow the search too. S is the most frequent final letter at 40 words, exactly twice the 20 ending in Y. Six finish with E and another six with N, while L, T, G, and M account for smaller groups.

Scores, dictionary coverage, and the list’s limits

• Excursionizing tops the Scrabble scores at 33 points; axiomatization follows at 32.
• Oxyhaemoglobin, exoticizations, and oxyhemoglobins also score 32, giving several high-value alternatives.
• The average score is 26.2, but a strong tile total does not make these obscure long words easy to play.
• Only 74 entries have definitions, and none is common by the frequency cutoff; check your game's word list before relying on a technical form.
