I frequently come across words like versprechen, erhalten, beliefern. Because my vocabulary is limited, i can detect that the verbs sprechen, halten and liefern were spoken but i do not know what ver-sprechen, er-halten and be-liefern mean. Is there a definite meaning of prefixes like these?
How should i tackle this topic of prefixes so that when a verb with a prefix is spoken, i can guess/know what it would mean. Thanks
