Saturday, August 8, 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 · written by DeepSeek-V3.2

READ · OUT
proofread · readout · outline — other legal bridges may also count.

5 letters, then 4 letters.
PAPER · CLIP
wallpaper · paperclip · clipboard — at least 2 different legal bridges exist for this one, so a different answer may well have counted too.

Day 16 ran on Saturday, August 8, 2026. Its three bridges were PROOF to LINE, WALL to BOARD and HEAD to DATE. 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 READ then OUT, which gives proofread, readout and outline. The first gap is 4 letters, the second is 3.
Only one pair in the KEYSTONE word bank joins PROOF to LINE, so this bridge had a single accepted answer. The narrow end is usually the one to solve first.
The answer is PAPER then CLIP, which gives wallpaper, paperclip and clipboard. The first gap is 5 letters, the second is 4.
This bridge is not unique. KEYSTONE accepts 2 different pairs here and every one of them scores: PAPER · BACK 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 LINE then UP, which gives headline, lineup and update. The first gap is 4 letters, the second is 2.
Only one pair in the KEYSTONE word bank joins HEAD to DATE, so this bridge had a single accepted answer. The narrow end is usually the one to solve first.
OUT and LINE 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.
