The Spanish word 'chivo' meaning 'young goat' or 'kid' comes from 'chib', which was a call or sound used to summon goats in Spanish. This is an interesting example of how animal names can develop from the sounds used to call them, similar to how we might say 'here kitty kitty' to cats in English.

The word 'chivo' doesn't have many common etymologically related words in Spanish, as it comes from a simple calling sound. However, you might encounter related terms like 'chivato' (informer/snitch) which developed from 'chivo', possibly due to the association with goats' behavior.

While there aren't direct English cognates of 'chivo', it's worth noting that English also has some words derived from animal calls, though for goats we typically use words derived from Germanic sources like 'goat' and 'kid'.
