6-letter words with S as the 2nd letter and O as the 3rd letter

The sequence _SO___ produces a compact set led by several ISO words. ISOMER, ISOPOD, ISOBAR, ISOGON, and ISOHEL share that opening, while TSOTSI, PSORIC, and DSOBOS show other starts. No match is common, and the first tile quickly separates the candidates.

At a glance

• 15 matches fit the second- and third-position clues.
• Seven begin with I; P and T each begin three.
• ISOLEX leads at 13 points, followed by PSOCID at 11.
• Five matches end in S.
• Collins lists 15; ENABLE lists 9.

Which opening clusters appear in the matches?

Seven words begin with I, including ISOMER, ISOPOD, ISOBAR, and ISOGON. P and T each account for three openings, while D accounts for two. That makes the initial letter especially useful when sorting the fixed S-O sequence.

Several candidates share an ISO- opening but diverge afterward: ISOMER, ISOPOD, ISOBAR, ISOHEL, ISOLEX, and ISOLOG. The remainder include TSOTSI, TSORES, and PSORAS. No match is classed as common, so familiarity alone will not cover the pattern.

What do the score leaders have in common?

ISOLEX tops the list at 13 points. PSOCID follows at 11, and PSORIC scores 10; ISOPOD, ISOHEL, and DSOBOS each reach 9. The average is 8.4, with the most valuable options concentrated among less familiar vocabulary.

Five words end in S, the most frequent final letter; D and R each finish two. The endpoints vary even within this small set, so use the final clue to distinguish candidates rather than assuming the ISO opening determines the rest.

The six-letter frame is especially restrictive because the common-word count is zero. Even a word that looks familiar from another context still needs to match a tournament list.
