15-letter words with X as the 2nd letter

The shape is much narrower than a general 15-letter list: almost every entry begins with E, while a handful begin with O or A. Most end in S, and only two qualify as common words by our frequency measure. Expect specialist vocabulary rather than everyday choices.

How many 15-letter words with X as the 2nd letter?

• 83 entries match the 15-letter pattern with X in position two.
• 77 begin with E; the other listed starters are O and A.
• 46 entries end in S, making that the most common final letter.
• Only 2 entries rank as common words.
• Oxyphenbutazone leads the score list at 41 points.

Why do most X-second words start with E?

The opening EX accounts for 77 of the 83 matches. Examples include experimentation, extraordinarily, extracurricular, and excommunication, so familiar-looking prefixes lead into many long technical or descriptive words.

The remaining six begin with O or A: four start with O and two with A. Oxytetracycline and oxidoreductases show the O pattern; the much smaller groups mean an A- or O-starting clue leaves fewer candidates than EX.

Which 15-letter X words score highest?

Oxyphenbutazone tops the scoring list at 41 points. Extrajudicially, exoerythrocytic, experimentalize, and extemporization each score 35, so the highest result is six points ahead of the next group.

This is a tournament-dictionary list, not a practical everyday vocabulary set: only 2 entries rank as common words. Dictionary coverage also varies: Collins includes 81 matches, NWL2023 includes 65, and ENABLE includes 59. Check your game's word list before playing.

Definitions cover 67 of the 83 matching entries, and the average score across the set is 27.6. That average trails oxyphenbutazone's 41 by more than a dozen points, so the top result is an outlier rather than the typical value. Most of the remaining entries carry no everyday meaning for most players.
