I am struggling a bit with Italian articles. I found this video helpful. She teaches in Spanish, so it helps if you know Spanish, but even if you don’t, I believe you may find this helpful if you, too, are struggling with Italian article adjectives.
Also helpful… A student in the following note to me in an email:
The following comes from the Living Language book.
il is used before most nouns beginning with a constant example il tavolo, il letto
lo is used before:
1. words beginning with the letter s followed by a consonant (sp, st, sc, etc) example lo specchio
2. words beginning with the letter z example lo zio
l’ before all vowels example l’armadio, l’uomo, l’amico
in the plural:
il becomes I
lo and l’ becomes gli
