7-letter words with I as the 1st letter and S as the 5th letter

The pattern is I _ _ _ S _ _: the first tile is I and the fifth is S, while four positions remain open. That makes this a precise clue, not a broad search for words beginning with I. IMPOSED and INSISTS are recognizable fits, but only five matches are classed as common, so familiar options make up a small share.

How many 7-letter words have I first and S fifth?

• The pattern yields 43 tournament-dictionary words; Collins contains 42, NWL2023 has 36, and ENABLE has 34.
• Just five matches count as common, so familiar candidates such as IMPOSED and INSISTS are a minority.
• Twenty words end in S, compared with 8 ending in D; those endings account for most of the recorded final letters.
• The average score is 9.8 points, while INUKSUK reaches the highest score at 15.
• IMPOSED, INFUSED, IMPOSES, and INVESTS are among the clearest everyday-looking matches.

Which words make the pattern easier to spot?

IMPOSED, IMPOSES, and IMPASSE show how an I-M-P opening can fill the first three slots, while INSISTS and INVESTS take a different route. INFUSED and INFESTS put a consonant cluster before the fixed S. These examples give you several shapes to test against known letters without guessing at every open tile.

Endings offer another filter: 20 matches finish in S, and 8 finish in D. If the last square is known, check those groups first; other recorded endings include R, E, A, K, L, and M. Dictionary totals overlap and differ, so check your game's word list before playing an unfamiliar entry.

How should you use these seven-letter matches?

• For a crossword or rack, lock I into slot one and S into slot five before testing the four open positions.
• Try familiar candidates first: IMPOSED, IMPOSES, and INVESTS all fit, but their different endings matter when letters are fixed.
• For scoring, INUKSUK reaches 15 points; it is a less familiar option than IMPOSED, so check its spelling carefully.
• A seven-tile Scrabble play earns a 50-point bingo bonus, but the word still has to fit the board and your game's rules.
