prepositions

Hello I would just like a clarifications on some prepositions. Is the plural form of "un" "dei" and the plural form of "uno" "degli" or is it the inverse? I remember this was in a table of prepositions that I stumble upon a while ago, but sure I'm not if it is correct. Singular : un uno plural : dei degli

Ciao Gab, the Italian indefinite articles are singular masculine un uno feminine una (un') There is no plural form . "dei" and "degli" is the combination of the preposition "di" +article ("I" or "gli"). They are called "partitive article" which in English will be translated as "some". Example: -Vado in vacanza con dei compagni -Io go on holidays with some mates -Vado in vacanza con degli amici -I go on holiday with some friends. I hope this helps Ciao
