What does QUELLO and BELLO have in common?

Everybody knows that quello means that and bello means  nice , however you might have noticed that, from time to time, quello and bello are in used in a different shape, like bel e quel or begli and quegli

How come?

Well, let’s start from quello

First thing first, you should be able to distinguish when quello is used as a pronoun (replacing a noun) and when used as adjective (accompanying a name).

In the first case, quello has four different possible endings, -o/-a/-i/e, according to the noun to which it refers

  • Quello è il mio gatto – That one is my cat
  • Quelle sono le mie amiche – those are my girlfriends

In the second case, when quello is an adjective, it changes its endings, by merging its root with the definite articles {il, lo, la, i, gli, le) that would normally precede a noun, as in the following examples:

  • Quei ragazzi
  • Quegli amici
  • Quell’uomo
  • Queragazzo
  • Quella donna
  • Quelle ragazze

The adjective bello follows exactly the same pattern of quello

  • Bei ragazzi
  • Begli amici
  • Bell’uomo
  • Bel ragazzo
  • Bella donna
  • Belle donne

The rule I have just mentioned, it to be applied just when quello and bello are positioned before a noun, that is to say that they must be adjectives to the noun.
