Italian can change the size and the mood of almost any noun with a suffix — the alterati. You'll hear them in every casual conversation:

Suffix	Effect	Examples
-one / -ona	big, often admiring	cane → cagnone · bello → bellone · macchina → macchinona
-ino / -ina	small, affectionate	cane → cagnolino · caffè → caffettino · mamma → mammina
-etto / -etta	small, cute	casa → casetta · borsa → borsetta
-accio / -accia	bad, nasty	tempo → tempaccio · parola → parolaccia (swear word)

Some have become words of their own: il telefonino (mobile phone), il panino (sandwich, from pane), il fumetto (comic). And a few switch gender with -one: la porta → il portone (main door).
