UNIT THREE Adjectives; possessive and demonstrative pronouns 1 Adjectives in Italian must agree in gender and number with the noun they refer to: if the noun is masculine singular the adjective must be masculine singular, if the noun is feminine singular the adjective must be feminine singu- lar, etc. Adjectives therefore change their forms accordingly. But remember that when an adjective is listed in a dictionary or a grammar, it is given in its masculine singular form. In the masculine singular, most Italian adjectives end in  -o  or in  -e : 2 Adjectives ending in  -o  have four di ff erent forms:  -o  for the masculine singular ( italian o ),  -a  for feminine singular ( italian a ),  -i  for the masculine plural ( italian i ) and  -e  for the feminine plural ( italian e ): 3 Adjectives ending in  -e  have only two forms:  -e  for the masculine and feminine singular ( frances e ) and  -i  for the masculine and feminine plural ( frances i ). With adjectives ending in  -e  there is thus no di ff erence between the masculine and the feminine form: l’arbitro  [ms]  italian o gli arbitri  [mp]  italian i la cameriera  [fs]  italian a le cameriere  [fp]  italian e lo stadio  [ms]  nuov o gli stadi  [mp]  nuov i la casa  [fs]  nuov a le case  [fp]  nuov e the Italian referee the Italian referees the Italian waitress the Italian waitresses the new stadium the new stadia/stadiums the new house the new houses italiano nuovo francese grande Italian new French big
