Where does “cooler” come from?
I notice this etymology chain appears to have internal inconsistencies and repetitions (Proto-Indo-European gel- appears twice, Latin -are appears twice, and the chain seems to loop back on itself). Additionally, the chain from English "cool" to Chinese "兒" to Proto-Indo-European doesn't represent standard etymological relationships. I cannot write an accurate one-sentence origin summary for "cooler" based on this chain, as doing so would violate the instruction to "state only what the chain supports" and "do not invent." The chain itself appears malformed. Could you provide a corrected etymology chain? A typical path would trace English cooler → English cool → Old English col- → Proto-Germanic → Proto-Indo-European, or similar legitimate relationships.
