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

The fixed letters create a narrow seven-character frame: I _ _ P _ _ _. Ten words match across tournament dictionaries, but their familiarity varies sharply. INSPIRE and INSPECT are recognizable; entries such as ISOPACH and INEPTER are less everyday. The constraint is much tighter than nearby patterns, so check the fourth slot before chasing another opening letter.

7-letter words with I first and P fourth: at a glance

• Ten tournament-listed words fit, including INSPIRE, INSPECT, ICEPACK, and ISOPODS.
• Only two of the ten are classified as common in English frequency data.
• The mean Scrabble score is 11.6 points; ICEPACK leads at 17.
• Three matches end in S, while two end in Y; five other endings occur once each.
• Collins includes all ten; NWL2023 includes nine, and ENABLE includes eight.

Which familiar words fit this letter pattern?

INSPIRE and INSPECT are the clearest familiar-looking choices, and both show how the fourth-position P can sit inside ordinary verb forms. INAPTLY and INEPTLY make a contrasting pair: each ends in -ly, but their middle letters differ, so one familiar ending does not solve the whole pattern.

Three words finish in S: ISOPODS, INKPOTS, and INSPANS. INAPTLY and INEPTLY account for the two Y endings; the remaining five final letters appear once apiece. That distribution makes the final slot a poor shortcut: checking positions one and four first narrows the search faster.

The contrast with other starting letters is striking: S-first words with P fourth number 197, compared with just 10 for I.

How do the matches score, and where are they accepted?

ICEPACK scores 17 points, ahead of ISOPACH at 14 and INKPOTS at 13. INAPTLY and INEPTLY each score 12, while INSPECT scores 11. These are base word scores, so a premium square can change the board result.

For 7-letter words with I first and P fourth, dictionary coverage is not identical: Collins has all 10 matches, NWL2023 has nine, and ENABLE has eight. The pattern is complete in Collins, but not universal across North American and ENABLE-based games; check your game's lexicon before challenging.
