The Spanish word 'chele' comes from the Nahuatl (Aztec) word 'celic', meaning 'green' or 'tender'. This is one of many words that Spanish borrowed from the indigenous languages of the Americas during the colonial period. The Nahuatl word was adapted to Spanish pronunciation patterns, with the 'c' sounds shifting to 'ch' at the beginning and the final 'c' being dropped, resulting in 'chele'.

While 'chele' is itself a relatively uncommon word in most Spanish dialects, it's worth noting that there aren't many commonly used Spanish words that share this Nahuatl etymology, as it comes from an indigenous American source rather than the usual Latin or Greek roots of most Spanish vocabulary.

There aren't any etymologically related English words to 'chele', as it comes from Nahuatl, an indigenous language family of Mexico, rather than from the Indo-European language family that gave rise to both English and most Spanish vocabulary. However, English speakers might find it interesting that this word represents one of many contributions from Native American languages to modern Spanish vocabulary.
