I tackle LinkedIn Crossclimb #891 in three passes — middles first, ordering second, combo ends last. This 4-letter board runs MAMA → … → PAPA with combo clue "Two of the very first words a baby might speak, or the people who might hear them.".
Middle phase: I work clues in board order — "Mesoamerican civilization known for its calendar and pyramids, as at Chichén Itzá" → MAYA; "Months after Aprils" → MAYS; "Puts the money up, as for a meal" → PAYS; "Expected scores on a golf course" → PARS; "Prefix before "phrase," "medic," or "chute"" → PARA.
Ordering phase: the valid middle chain is MAYA → MAYS → PAYS → PARS → PARA. This permutation is the only valid one-letter chain for these answers.
I verify MAMA to MAYA — M→Y at the third letter (MAMA → MAYA).
I verify MAYA to MAYS — A→S at the fourth letter (MAYA → MAYS).
I verify MAYS to PAYS — M→P at the first letter (MAYS → PAYS).
I verify PAYS to PARS — Y→R at the third letter (PAYS → PARS).
I verify PARS to PARA — S→A at the fourth letter (PARS → PARA).
I verify PARA to PAPA — R→P at the third letter (PARA → PAPA).
Finished chain: MAMA → MAYA → MAYS → PAYS → PARS → PARA → PAPA. Combo ends MAMA + PAPA clicked once ordering locked. Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
