21 five letter words begin with IS, and nearly a third of them take L as the third letter.

L Leads the IS Third Box

L takes about twenty nine percent, then I at fourteen, and A, O and a second S at ten each.

The IS Words in Ordinary Use

ISSUE is the entry you are almost certainly after. ISLES and ISLET follow it, both on that leading L branch.

Everything else on the page is a place name, a religion or an obsolete form, so three words is the realistic list.

That makes this one of the thinnest pages in the set once the names are set aside.

The Silent S in ISLES and ISLET

Both put an S you do not pronounce in the second box, so the word sounds as though it begins with a long I. That is why players misplace the letters here.

ISSUE has no such trap, which is part of why it comes to mind so much faster than the other two.

Treating the IS Page as a Check

Guess ISSUE first. If it does not fit, ISLES and ISLET are the only realistic alternatives left on the page.

Frequently Asked Questions

Why is the S silent in ISLES

The word came through French from Latin insula, and English kept the S in the spelling long after it stopped being said.

What separates ISLES from ISLET

Only the last two boxes. Both share ISL, so a guess on either narrows the other to a single question.

Does ISSUE repeat a letter

Yes, it doubles the S across the second and third boxes. That doubling is ten percent of the page on its own.
