KEYSTONE · Day 45

Sunday, September 6, 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

BLACK→???→????→WAY

3 letters, then 4 letters.

Show an answer

OUT · DOOR

blackout · outdoor · doorway — at least 3 different legal bridges exist for this one, so a different answer may well have counted too.

Main

MORE→????→????→LIGHT

4 letters, then 4 letters.

Show an answer

OVER · HEAD

moreover · overhead · headlight — other legal bridges may also count.

Challenge

WHOLE→????→????→NOT

4 letters, then 4 letters.

SOME · WHAT

wholesome · somewhat · whatnot — other legal bridges may also count.

How day 45 worked out

Day 45 ran on Sunday, September 6, 2026. Its three bridges were BLACK to WAY, MORE to LIGHT and WHOLE to NOT. 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: BLACK to WAY

The answer is OUT then DOOR, which gives blackout, outdoor and doorway. The first gap is 3 letters, the second is 4.

This bridge is not unique. KEYSTONE accepts 3 different pairs here and every one of them scores: OUT · RUN and BOARD · WALK 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: MORE to LIGHT

The answer is OVER then HEAD, which gives moreover, overhead and headlight. The first gap is 4 letters, the second is 4.

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

Challenge: WHOLE to NOT

The answer is SOME then WHAT, which gives wholesome, somewhat and whatnot. The first gap is 4 letters, the second is 4.

Only one pair in the KEYSTONE word bank joins WHOLE to NOT, so this bridge had a single accepted answer. The narrow end is usually the one to solve first.

Every compound word in day 45

OUT, DOOR, OVER, HEAD and SOME 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.
