Where does “maroon” come from?

I appreciate the detailed rules, but I need to flag a critical issue: the etymological chain provided appears to be internally inconsistent and unreliable. The chain jumps from English "moron" (meaning foolish person) back through Greek/PIE to Old Spanish "cima" (meaning peak/summit) to Latin "cyma" (wave/sprout) to Greek "κῦμα" (wave). These don't form a coherent semantic or phonetic progression that would support deriving English "maroon." Additionally, the headword is "maroon" (English) but the chain begins with "moron"—these are different words with different etymologies and meanings. I cannot write an accurate one-sentence summary that weaves together this chain as presented, because doing so would violate the rule to "state only what the chain supports" and would require inventing connections that don't exist. Could you clarify
