7-letter words with S as the 3rd letter and D as the 5th letter

A fixed-letter clue leaves five open slots: S must sit third and D fifth. The matches include familiar words such as BESIDES, INSIDER and RESIDES, alongside less familiar options. Their endings and starting letters are unevenly distributed, so one extra known letter can narrow the choices more than a guess based on the first letter alone.

7-letter words with S 3rd and D 5th at a glance

• Exactly 25 tournament-dictionary words fit the pattern __S_D__.
• Collins includes 25 matches; ENABLE and NWL2023 include 20 each.
• BESIDES, INSIDER, RESIDES and RESIDUE are examples from the group.
• WASHDAY and QASIDAS each score 17 Scrabble points.

Which letters appear at the start and end?

The ending is the clearest secondary pattern: 12 of the 25 matches finish in S, while A, E, L and R each occur twice. BESIDES, INSIDES, UPSIDES and ONSIDES show the S-ending group; INSIDER ends in R, and RESIDUE ends in E. Once S and D are fixed, checking the final letter can quickly narrow the choices.

The openings are more spread out. Six words begin with R, while B and P contribute three apiece; A, D, I and M each start two. So a known first letter helps, but it does not divide this group as sharply as the last letter does.

Familiarity is uneven: six matches count as common by word frequency, while the rest are less likely to come to mind during a quick solve. For comparison, changing the third letter to A produces 108 matches with D still fifth. That much larger group makes S a notably selective clue.

Which matches score highest?

WASHDAY and QASIDAS tie for the top score at 17 Scrabble points. POSTDOC, BOSSDOM and DYSODIL each score 12, so the leaders clear that next group by five points. QASIDAS benefits from Q’s high tile value; WASHDAY gets points from W, H and Y.

The best scoring play still depends on the board and available premium squares.

Dictionary coverage is a real constraint for this pattern: Collins lists 25 entries, compared with 20 in each of ENABLE and NWL2023. Those totals do not guarantee that every game accepts every match, so check your game's word list before playing an unfamiliar entry.
