Wool is the same word in Italian and Spanish: la lana.
You can add meaning to this word by associating it with Adam Lallana, the footballer. His paternal abuelo is actually from Madrid, Spain. Fun fact: the Catalan word for wool is llana with two L's.
Lana - wool
Sciarpa di lana - wool scarf
Lana d'acciaio - steel wool
Lana caprina - piddling; a moot point
Sul filo di lana - down to the wire
