7-letter words with S as the 3rd letter and I as the 4th letter

The fixed pattern is _ _ S I _ _ _, and it produces 138 eligible seven-letter entries. Familiar options include BESIDES, MUSICAL, VISITED, VISIBLE, and INSIGHT, while the high-scoring edge case WYSIWYG is much less ordinary. The list spans tournament dictionaries unevenly, so a familiar-looking answer is not automatically accepted in every game.

At a glance: the S-I pattern

• 138 words fit the two fixed middle letters and seven-letter length.
• Collins contains 137 matches; NWL2023 has 103, while ENABLE has 96.
• Only 25 entries rank among the top 25,000 English words by frequency.
• R is the leading first letter, with 29 matches; V follows with 14.
• WYSIWYG scores 20, ahead of UPSIZED at 19 and UPSIZES at 18.

Which endings and first letters stand out?

Words ending in S dominate: 61 of the 138 matches use that final letter. DESIGNS, ASSISTS, DESIRES, and VISIONS show how often this pattern lands on a plural or verb form. The next endings are D with 17 and T with 13, so an S ending is common but hardly compulsory.

At the other end, R starts 29 words, more than V's 14. RESIDES, RESIDUE, RESIZED, and RESIZES make that opening especially productive; B contributes 13, with A close behind at 12. After confirming _ _ S I, test R first when the opening tile remains unknown, but keep V and B in play.

These words average 9.9 points. WYSIWYG tops the score ranking at 20, followed by UPSIZED at 19 and UPSIZES at 18. Those totals make the W and Y tiles stand out; a premium square can raise a play's board result, but it does not change a word's base score.

Only 25 entries are common by the frequency cutoff, and dictionary coverage differs: Collins includes 137, compared with 103 in NWL2023 and 96 in ENABLE. Treat the pattern as a solving pool, not a promise that every entry works in every app. Check your game's word list before committing an unfamiliar form such as WYSIWYG or QASIDAS.
