Bonsoir
Complétez avec les adjectifs possessifs.
as you know, in French possessive agre with the noun they describe, which is after
Il voyage avec.....son...... amie
this is a tricky one !!!! "amie" is feminine singular = sa
BUT sa + amie = two vowels !! It does'nt work that' why we 're going to say "son amie" and use the masculine possessive
In this rule when a feminine noun begins with a vowel, the noun’s possessive adjective is formed in the masculine form for pronunciation reasons.
hope this helps :)
