Friday, September 18, 2026 — three word bridges.
SOME → DAY → LIGHT → HOUSE works because someday, daylight and lighthouse are all words. You are given the two ends; you supply the middle. More than one bridge is often legal, and any legal bridge counts.Warm-up
3 letters, then 4 letters.
OUT · BACK
timeout · outback · backyard — other legal bridges may also count.
Main
4 letters, then 3 letters.
FALL · OUT
nightfall · fallout · outcast — at least 2 different legal bridges exist for this one, so a different answer may well have counted too.
Challenge
4 letters, then 4 letters.
TAKE · OVER
undertake · takeover · override — at least 2 different legal bridges exist for this one, so a different answer may well have counted too.
Day 57 ran on Friday, September 18, 2026. Its three bridges were TIME to YARD, NIGHT to CAST and UNDER to RIDE. Between them they build nine compound words, all listed at the bottom of this page. Below is the answer to each bridge and what makes it fit.
The answer is OUT then BACK, which gives timeout, outback and backyard. The first gap is 3 letters, the second is 4.
Only one pair in the KEYSTONE word bank joins TIME to YARD, so this bridge had a single accepted answer. The narrow end is usually the one to solve first.
The answer is FALL then OUT, which gives nightfall, fallout and outcast. The first gap is 4 letters, the second is 3.
This bridge is not unique. KEYSTONE accepts 2 different pairs here and every one of them scores: TIME · OUT works just as well as the pair above. Ends like these sit in the crowded part of the compound-word network, which is why several routes cross them.
The answer is TAKE then OVER, which gives undertake, takeover and override. The first gap is 4 letters, the second is 4.
This bridge is not unique. KEYSTONE accepts 2 different pairs here and every one of them scores: PASS · OVER works just as well as the pair above. Ends like these sit in the crowded part of the compound-word network, which is why several routes cross them.
OUT, BACK, FALL, TAKE and OVER have a page listing every compound built on them and the other chains you can run through them.
Every one of those nine compounds turns on a hinge word doing double duty. If you want to see the whole set KEYSTONE draws from, the reference list of 141 compound word hinges gives the words that attach in front of and behind each one.
