Position two gives these long words a shared pattern, but their beginnings and endings vary sharply. P is the most common first letter, while S dominates the final position. The list also spans distinct fields: parliamentarian is political, pathophysiology is medical, and paleontologists covers prehistoric life; none falls in the common-word group, so expect specialist vocabulary rather than everyday choices.

15-letter words with A as the 2nd letter at a glance

The pattern contains 419 words, all with A in position two.
Parliamentarian, nationalization, and rationalization are prominent examples.
P leads the first-letter counts with 106 words; M follows with 71.
S is the strongest final-letter clue: 256 words end in S, compared with 47 ending in Y.
The list has 293 entries with definitions, but none in the common-word group.

Which first letters appear most often?

P accounts for 106 words, well ahead of M at 71. C and R are the next substantial groups, with 39 and 38 entries respectively. If you know both the second and first letters, a P-starting candidate is the strongest place to begin.

That P group is not one narrow word family. Parliamentarian, parasympathetic, paleontologists, and pathophysiology all begin with PA, yet point to politics, biology, fossils, and medicine. Their shared letter pattern offers a clue; the subject matter does not.

Which entries score highest?

Tachyarrhythmia, kaffeeklatsches, and mathematicizing tie for the top score at 34. Haphazardnesses and laryngectomized follow at 33, while pathophysiology scores 32. These are strong tile-value candidates, though a board's premium squares still affect the final play.

The average score is 22.6, but the top scorers are not everyday words: none of the entries meets the common-word cutoff. Dictionary coverage also differs, with Collins including 399 entries against 239 in NWL2023 and 185 in ENABLE.

Those dictionary totals overlap, so they are not separate piles to add together. Check your game's word list before playing a specialist term.

Questions people ask

Are all 419 words accepted in every word game?

No. The 419-word count includes words found in at least one tournament dictionary, not necessarily every dictionary. Collins includes 399 entries, while NWL2023 includes 239 and ENABLE includes 185. Those sets overlap, so check the specific word list your game uses before relying on an entry.

Which starting letter is most common in this list?

P is the most common first letter, with 106 entries. M comes next with 71, followed by C with 39 and R with 38. Parliamentarian and pathophysiology are recognizable examples of the P group, which is much larger than any other starting-letter group.

What is the highest-scoring 15-letter word with A second?

Tachyarrhythmia, kaffeeklatsches, and mathematicizing share the highest score, at 34 each. Haphazardnesses and laryngectomized score 33, and pathophysiology scores 32. Board placement can change a play's total, even when the word's tile score is high.
