Thanks, but I really struggle to know? I have read all sorts of articles on the internet but no luck. Can not figure it out? Is there any easy way?
Yes, if a verb is transitive then it most often connects with Accusative without any preposition (some verbs connect with Genitive). English follows SVO word order so if there is a noun/pronoun before and after a verb in English sentence then you can assume that the verb is transitive and the direct object of the verb will appear in Accusative. In Polish the subject of the sentence is implied in the verb form.
