Especially in Spanish where “verb classes” already exist and have distinct, if subtle, rules (-ar, -er and -ir)

Don’t they call it “conjugations” in Spanish too?
Note however that they work in a really different way, more like noun declensions than like noun classes=gender. For example, you don’t trigger agreement; even if you were to replace an -ar verb with an -er or -ir verb, the rest of the sentence stays the same.
