Explanation
Some plurals change spelling because Italian spelling has to match the sound. Words in -co/-go: if stressed on the next-to-last syllable (piane) they usually keep the hard sound with -chi/-ghi (fuoco → fuochi, albergo → alberghi); if stressed earlier (sdrucciole) they usually soften to -ci/-gi (medico → medici). But this is a tendency, not a law: amico → amici and greco → greci break it. Words in -cia/-gia: keep the i after a vowel (camicia → camicie, valigia → valigie) but drop it after a consonant (spiaggia → spiagge, arancia → arance). Words in -io with unstressed i take a single -i (figlio → figli, negozio → negozi); if the i is stressed, you get -ii (zio → zii).

Note
The -co/-go plural is the one to memorize word by word — the stress rule only predicts, it doesn't guarantee (amico breaks it). The -cia/-gia rule is reliable: look at the letter just before -cia. When in doubt, check a dictionary rather than guess.
