A fixed second letter creates a surprisingly varied set: the entries range from familiar words such as ESTABLISHMENT to specialist terms such as OSTEOmyelitis. Most begin with P or A, but I, E, and O also contribute sizeable groups. Only six entries rank among the most common English words, so expect a mix of recognizable vocabulary and demanding tournament plays.

What stands out in 13-letter words with S as the second letter?

There are 209 qualifying words across the tournament dictionaries counted here.
P leads the first-letter group with 67 entries; A follows with 58.
Only six entries fall within the top 25,000 English words by frequency.
ESTABLISHMENT and PSYCHOLOGICAL are recognizable examples among the long terms.
PSYCHOANALYZE tops the scoring examples at 35 points.

Which openings and endings dominate?

P begins 67 of the entries, A begins 58, and I begins 34. That makes P and A strong places to test when your pattern leaves the first letter open. Examples include PSYCHOLOGICAL, PSYCHOTHERAPY, ASSASSINATION, and ISOLATIONISTS.

The final letter is even more concentrated: 112 words end in S, while Y is next with 21. Plurals and other S-ending forms account for many of the familiar-looking options, including PSYCHOLOGISTS and OSCILLOSCOPES. An ending clue can narrow the search sharply.

Which S-second words score highest?

PSYCHOANALYZE leads the scoring examples at 35 points, followed by PSYCHOLOGIZED and ISOCARBOXAZID at 34 each. PSYCHOPHYSICS and PSYCHOLOGIZES each score 33. These are demanding plays, but the score list shows how unusual letters in long words can outweigh their length alone.

The 209-word total pools entries found in at least one of Collins, NWL2023, or ENABLE; their individual counts are 202, 132, and 118. Those source counts are not separate piles to add together.

Check your game's word list before playing a specialist term. The average score is 20.9, but many entries are obscure rather than everyday choices.
