7-letter words with B as the 2nd letter and S as the 3rd letter

That exact letter lock leaves just 18 tournament-dictionary entries. Thirteen start with A and five with O, so the B-S pair narrows the search before the final four letters matter. ABSENCE, ABSOLVE, OBSERVE, and OBSCURE are familiar anchors; the rest range from everyday forms to specialist vocabulary.

How the B-S pattern breaks down

• Collins includes all 18 matches; ENABLE and NWL2023 include 15 each.
• Thirteen begin with A and share the opening ABS; the other five begin with O and open OBS.
• Only 5 matches rank among the top 25,000 English words by wordfreq frequency.
• OBSEQUY scores 21 points, far ahead of the next scorers at 12.
• Seven matches end in S, while six end in E.

Why do most matches begin with A?

A begins 13 of the 18 words, and every A-starter starts ABS: ABSENCE, ABSORBS, ABSTAIN, and ABSOLVE are easy examples to recognize. That repeated opening means the clue’s fixed second and third letters often come bundled with a first-letter clue.

The five O-starters all open OBS. OBSERVE and OBSCURE are familiar choices, while OBSEQUY is the standout scorer. Once you know the first letter, the remaining candidates fall into two compact groups rather than a scattered set.

The endings split almost as tightly: S closes 7 words and E closes 6. ABSENCE and OBSERVE show the E ending; ABSORBS and ABSENTS show the S ending.

Which matches score well, and where does the pattern fall short?

OBSEQUY leads the scores at 21 points. OBSERVE, ABSOLVE, ABSCOND, ABSINTH, and ABSCIND each score 12, so the unusual O-word beats the next group by 9 points before any premium board squares.

Frequency is the main limitation: only 5 entries are common by the wordfreq measure. Collins has all 18, but ENABLE and NWL2023 each have 15, so check your game’s word list when an unfamiliar entry matters.

For a nearby comparison, the seven-letter B-second, R-third pattern has 20 entries, while the B-second, U-third pattern has 10. The 18 7-letter words with B as the 2nd letter and S as the 3rd letter sit between those counts, with OBSEQUY as their rare high-scoring surprise.
