7-letter words with I as the 1st letter and U as the 4th letter

Every match follows I??U??: the first and fourth positions are fixed, while the other five letters vary. Familiar examples include INJURED, INQUIRY, INSULIN, and IMPULSE, but frequency is the catch: just 15 of the 74 are classed as common. Treat the pattern as a way to narrow a seven-letter rack, not as a promise that every candidate will feel familiar.

At a glance: the I??U?? pattern

• All 74 matches put I first and U fourth, giving the fixed shape I??U??.
• INJURED, INQUIRY, INDUCED, and INSULIN are recognizable examples.
• Just 15 of the 74 are classed as common, leaving most entries outside everyday vocabulary.
• Collins includes 73 matches, while NWL2023 includes 65 and ENABLE includes 58.
• INQUIRY leads the scoring list at 19 points.

Which I-first, U-fourth words score most?

INQUIRY is the standout scorer at 19 points. INQUIRE, INQUEST, INJUNCT, INQUIET, and INQUERE each score 16. Those totals reward the Q and J, not just the familiar I-N opening; a premium square can raise the board score further.

INJURED scores 15, while INJURES scores 14, so you have options beyond the Q-and-J group. INQUIRY is a strong rack score, but its Q and Y can be awkward to unload if the board blocks the placement. A legal fit matters more than the face value alone.

How do word endings narrow the pattern?

Endings are lopsided: 28 matches finish in S, compared with 10 in D and nine each in E and R. The S-heavy tail includes INSULTS, ISSUERS, and INSURES; INJURED, INDUCED, and IMPUTED show the D ending. If your rack suggests a suffix, check those endings before changing the fixed U.

Dictionary coverage is uneven: Collins includes 73 entries, NWL2023 includes 65, and ENABLE includes 58. A candidate accepted in one game's lexicon can fail in another, so check your game's word list before spending a turn on an obscure form.

Changing only the first letter gives a larger comparison set: 142 seven-letter words start with S and keep U fourth, versus 74 with I. Keeping I and shifting the fourth slot to T gives 25 matches, making U a middle-sized option for this pattern.
