In reply to:

An example of confused gender is the Italian word mano = hand. It is declined as if masculine (singular mano, plural mani), but it is actually feminine gender


Many of the Italian words for parts of the body are irregular, in their plural forms and/or gender. A fact I as pleased to be able to point out to my English students in Italy when they complained about the irregular spelling and/or plurals of so many of the English words in the same lexical set!

Some examples:
Italian for lip: labbro (sing, masc); while lips: labbra (plur, fem)

Italian for foot: piede (sing,fem); feet: peidi (plu, fem)

While in English we have irregular plurals and some of the most irrational spellings:
tooth teeth
foot feet
eye (spelling!)
tongue (spelling!)
-etc
