Words aren’t gendered in Spanish/French/German/etc. It’s called “grammatical gender” but it’s just a way some languages differentiate words/word forms and do adjective/noun/verb agreement, it’s only sometimes loosely correlated with actual gender and is often contradictory when it’s used on living beings.

For example, many words which are used to describe women or female animals in such languages are masculine or neuter gender. Many times words for living things will have one class regardless of the actual gender.

Some grammatical gender types which might make more immediate sense are animacy (animate/inanimate, usually correlated with biotic/abiotic), human/animal/inhuman, countable vs uncountable (the difference between “a plant is here” vs “a water is here”, the second one isn’t grammatically correct in standard English because “water” is an uncountable noun, same with “furniture”, “wind”, “energy”).

A word that a lot of people prefer to use rather than “grammatical gender” is “noun class”, it more clearly conveys what the actual use of that sort of thing in language is. “Grammatical gender” is a pretty outdaded name for it, it was called that in a time where “gender” was more broadly used to mean any class/enumeration/kind/variants/etc. (it has the same root as the word “genre” if that helps it make sense). Only way after the term was coined did “gender” start to refer to what it does now.
