Giacomo  mi  invita spesso a cena. Se vuoi,  ti  aiuto. Lo  conosco bene. La  vedo tutti i giorni. Vi  invito alla festa. Giacomo often invites  me  to dinner. If you want, I’ll help  you . I know  him  well. I see  her  every day.

I know  them  well.’ ‘Do you use the computer and the printer?’ ‘Yes, I often use  them .’ 3 We saw in Unit 3 that if an adjective refers to two or more nouns that are di ff erent in gender, it has the masculine plural form, e.g.  Laura e Piero sono italian i  (Laura and Piero are Italian). The same principle applies to direct object pronouns: 5 When a direct object pronoun is used with a verb in the in fi nitive (usually after verbs like  dovere ,  potere ,  volere  or  sapere ), it can be attached to the in fi nitive, which drops the  fi nal vowel: Each pair of sentences has exactly the same meaning – the form used makes no di ff erence. * Note that verbs in  -urre  drop the second  r  as well as the  fi nal vowel:  lo devo tradurre or devo tradurlo . La  devo chiamare. Ti  voglio invitare. Lo  puoi prendere. Lo  so fare. Lo  devo tradurre. * or or or or or Devo chiamar la. Voglio invitar ti. Puoi prender lo. So far lo. Devo tradur lo . * I must call her. I want to invite you. You can take it. I can/know how to do it. I’ve got to translate it. Non  lo  conosco bene. Non  vi  invito alla festa. Non  li  vedo spesso. Non  ti  capisco. I don’t know him well. I’m not inviting you to the party. I don’t often see them. I don’t understand you. 4 The negative is formed by putting  non  before the pronoun: Negative form Unit 7 53
