"Her socks are gray."
Translation:Le sue calze sono grigie.
the noun 'sock' is masculine. It's only feminine if it's a knee sock. The sentence says, 'sock, not knee sock. The posessive takes the gender of that which is posessed, not the posessor.
Even if it is a girl (her) you still side with the gender and quantity of the noun.... which in this example (socks) is masculine and plural.
"grey" is the British English spelling, and "gray" is the American English spelling of the same word.
No, it's feminine. It follows almost all the same endings as the articles. «il, lo, i, gli» are masculine articles, so the masculine possessives are «il suo, i suoi». The feminine articles are «la, le», so the feminine possessives are «la sua, le sue».
in a previous sentence the correct answer was " vestito violA " i.e not in agreement but this one has " calza griggie " in agreement. Perche?
