LinkedIn Crossclimb #780 is a 4-letter Crossclimb ladder from HUGE to VAST. Phase one is crossword solving: 5 middle clues yield HUGS, PUGS, PUSS, PASS, PAST. Phase two is ordering; phase three unlocks the combo ends tied by "The words to describe something of extremely great size or scope.".
Middle phase answers: "Embraces in one's arms" = HUGS; "Dogs with wrinkly, flat faces" = PUGS; ""____ in Boots" (fairy tale with an anthropomorphic cat)" = PUSS; "Do well enough to clear an examination in school" = PASS; "Future's opposite" = PAST.
Ordering phase: the valid middle chain is HUGS → PUGS → PUSS → PASS → PAST. This permutation is the only valid one-letter chain for these answers.
Link HUGE → HUGS: E→S at the fourth letter (HUGE → HUGS) (combo-adjacent).
Link HUGS → PUGS: H→P at the first letter (HUGS → PUGS).
Link PUGS → PUSS: G→S at the third letter (PUGS → PUSS).
Link PUSS → PASS: U→A at the second letter (PUSS → PASS).
Link PASS → PAST: S→T at the fourth letter (PASS → PAST).
Link PAST → VAST: P→V at the first letter (PAST → VAST) (combo-adjacent).
Complete ladder: HUGE → HUGS → PUGS → PUSS → PASS → PAST → VAST. The combo clue "The words to describe something of extremely great size or scope." describes both end words together — "HUGE" and "VAST" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt. Pattern: unique middle order — Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
