"I am giving him my eyeglasses."
Translation:Daję mu moje okulary.
it should be swoje instead of swoi
swoi is the masculine personal form (so like for groups of male people only) and swoje is used for everything else (provided it's plural ofc)
Ok how is it "mu" this time. And where I can I finf all the list of form for him for example and when to. Use them. Everyone I think I've got one word I find out I haven't :(
https://en.wiktionary.org/wiki/Appendix:Polish_pronouns#General for all the forms, it's harder to say when to use which.
"mu" is Dative. The verb "dawać" (to give) takes Dative for the indirect object and Accusative for the direct object.
There are also two alternative Dative forms for "him": "jemu" and "niemu", but the first one is emphatic and there's no reason for emphasis in this sentence, and the other one is used only after prepositions.
