Case file LinkedIn Crossclimb #797: 4-letter ladder, 5 middle exhibits, combo prompt "A compound word that means “goodbye” or “have a good trip.”". Endpoints: FARE (top) and WELL (bottom).
Middle phase answers: "Land area used for agriculture" = FARM; "Solid and unwavering, or a group of attorneys doing business together" = FIRM; "Motion picture shown in a cinema" = FILM; "___-in-the-blank" = FILL; "Mental resolve or determination" = WILL.
Ordering phase: the valid middle chain is FARM → FIRM → FILM → FILL → WILL. This permutation is the only valid one-letter chain for these answers.
Evidence link: FARE → FARM. E→M at the fourth letter (FARE → FARM).
Evidence link: FARM → FIRM. A→I at the second letter (FARM → FIRM).
Evidence link: FIRM → FILM. R→L at the third letter (FIRM → FILM).
Evidence link: FILM → FILL. M→L at the fourth letter (FILM → FILL).
Evidence link: FILL → WILL. F→W at the first letter (FILL → WILL).
Evidence link: WILL → WELL. I→E at the second letter (WILL → WELL).
Verdict: FARE → FARM → FIRM → FILM → FILL → WILL → WELL satisfies every one-letter constraint. The combo clue "A compound word that means “goodbye” or “have a good trip.”" describes both end words together — "FARE" and "WELL" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt.
