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

Locking I into the first slot and S into the last leaves three open letters, yet the full pattern yields just 32 tournament-list words. IDEAS, ITEMS, and ICONS are familiar footholds; IZARS is the scoring standout at 14. Only 6 entries meet the common-word cutoff, so solving by pattern alone quickly runs into less familiar vocabulary.

5-letter words with I first and S last

• Exactly 32 tournament-dictionary words start with I and end with S.
• IDEAS, ITEMS, ICONS, ISLES, and IDOLS are among the recognizable entries.
• Six entries qualify as common, about one in five of the 32; most are less familiar.
• None is a Wordle answer, though 31 are accepted as allowed guesses.
• The average score is 7.5 points; IZARS leads the set at 14.

Which I-starting words ending in S score highest?

IZARS tops the score chart at 14 points, ahead of IXIAS at 12. ICHES follows with 10, while IMAMS, IKONS, IAMBS, IMPIS, IDYLS, IKATS, and IKANS each score 9.

That makes IZARS the standout for raw letter value, but the rack still matters. Choose it when the Z fits your play; a strong score is no reason to force an awkward placement.

The middle letters also separate familiar options from specialist vocabulary. IDEAS and ISLES place vowels in the middle, while ITEMS and ICONS offer recognizable forms. IDOLS and IRONS are two more everyday choices.

Entries such as INCUS, ILEUS, and ICTUS are less familiar. And although IDEAS and ITEMS are plurals, the final S does not make every match a plural word.

Keeping I fixed while changing the last letter gives 21 matches ending in E, 17 in T, and 14 in R, compared with 32 ending in S. If S is already fixed in your puzzle, this is the largest of those four patterns to check.
