KEYSTONE · Day 28

Thursday, August 20, 2026 — three word bridges.

Every neighbouring pair has to make one word. 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

MORE????????OUT

4 letters, then 4 letters.

Show an answer

OVER · LOOK

moreover · overlook · lookout — at least 6 different legal bridges exist for this one, so a different answer may well have counted too.

schoolgirl · girlfriend · friendship — at least 2 different legal bridges exist for this one, so a different answer may well have counted too.

BACK · SIDE

flashback · backside · sidewalk — at least 2 different legal bridges exist for this one, so a different answer may well have counted too.

How day 28 worked out

Day 28 ran on Thursday, August 20, 2026. Its three bridges were MORE to OUT, SCHOOL to SHIP and FLASH to WALK. 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.

Warm-up: MORE to OUT

The answer is OVER then LOOK, which gives moreover, overlook and lookout. The first gap is 4 letters, the second is 4.

This bridge is not unique. KEYSTONE accepts 6 different pairs here and every one of them scores: OVER · TIME, OVER · WORK, OVER · TAKE, OVER · LAY and OVER · TURN work 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.

Main: SCHOOL to SHIP

The answer is GIRL then FRIEND, which gives schoolgirl, girlfriend and friendship. The first gap is 4 letters, the second is 6.

This bridge is not unique. KEYSTONE accepts 2 different pairs here and every one of them scores: BOY · FRIEND 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.

Challenge: FLASH to WALK

The answer is BACK then SIDE, which gives flashback, backside and sidewalk. 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: BACK · BOARD 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.

Every compound word in day 28

OVER, BACK and SIDE 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.
