KEYSTONE · Day 24

Sunday, August 16, 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

HANG????????OUT

4 letters, then 4 letters.

Show an answer

OVER · LOOK

hangover · overlook · lookout — at least 8 different legal bridges exist for this one, so a different answer may well have counted too.

Main

4 letters, then 4 letters.

OVER · WORK

flyover · overwork · workroom — other legal bridges may also count.

Challenge

COUNT????????SIDE

4 letters, then 4 letters.

DOWN · HILL

countdown · downhill · hillside — at least 2 different legal bridges exist for this one, so a different answer may well have counted too.

How day 24 worked out

Day 24 ran on Sunday, August 16, 2026. Its three bridges were HANG to OUT, FLY to ROOM and COUNT to SIDE. 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: HANG to OUT

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

This bridge is not unique. KEYSTONE accepts 8 different pairs here and every one of them scores: OUT · BREAK, OUT · LOOK, 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: FLY to ROOM

The answer is OVER then WORK, which gives flyover, overwork and workroom. The first gap is 4 letters, the second is 4.

Only one pair in the KEYSTONE word bank joins FLY to ROOM, so this bridge had a single accepted answer. The narrow end is usually the one to solve first.

Challenge: COUNT to SIDE

The answer is DOWN then HILL, which gives countdown, downhill and hillside. 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: DOWN · RIVER 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 24

OVER, WORK and DOWN 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.
