And of course there is also the noun "guinzaglio" (meaning leash). Given the form of "add s to a verb to make it 'un'", you MIGHT think that there is also a verb "guinzagliare" (to put on a leash), but in fact there is not. There is the adjective "guinzagliato" (leashed), but to say "to put a dog on a leash" you'd say "mettere il guinzaglio al cane" or "legare il cane col guinzaglio." To have a person on a leash: "tenere qc al guinzaglio." There is no verb guinzagliare.
