I had answered on the notebooks...
"delle" is composed by the preposition "di" and the article "le" and it can have different meanings:
- 'complemento di specificazione': "of the" > "gli occhi delle donne..." = "the eyes of the women..."
- 'complemento di argomento' "about the" > "non è facile parlare delle donne" = "it isn't easy speaking about the women"
- intruduce the second term in comparatives: "than the" > "gli uomini sono piú robusti delle donne" = "[the] men are robuster than [the] women"
- partitive article: "some" > "delle donne sono venute..." > "some women have came..."
"Ho dei fiori" = "I have some flowers"
"Ho i fiori" = "I have the flowers" (the flowers, about which you already know)
