 Nominative pronouns only have the strong form (except in some minor environments) and are used as subjects only when special emphasis is intended, since unstressed subjects recoverable from context are not overtly expressed anyway.Genitive (possessive) pronouns are used in their weak forms as pre-verbal clitics to express indirect objects (for example, του μίλησα, , 'I talked to him'), and as a post-nominal clitic to express possession (for example, οι φίλοι του, , 'his friends').The strong genitive forms are relatively rare and used only for special emphasis (for example, αυτού οι φίλοι, , "'his" friends'); often they are doubled by the weak forms (for example, αυτού του μίλησα, , ' "him" I talked to').
