How many 14-letter words start with X?

The vocabulary explains the narrow pool. Examples include xenobiologists, xenotransplant, and xerophthalmias; others, such as xiphihumeralis and xylotypography, are even more specialized. Treat this as a clue-matching list, not a bank of familiar conversation words.

Which X starters score highest, and how do they end?

Xylopyrography and Xylotypography lead at 38 points apiece. Xerophytically follows at 34, then Xenophobically at 33. Those are base word scores; board premiums can change a play's total, so check the letter and word squares before judging a move.

Nine of the 15 entries end in S, making that the most common finish by a wide margin; Y accounts for four. In a rack or crossword clue, that S-heavy pattern is a better narrowing clue than guessing among all the unusual X vocabulary.
