When memorizing vocabulary lists, I found that I'm rather good at remembering nouns and adjectives, but verbs tend to slip my mind quite easily.* It's led me to wonder if others experience the same thing: that is, as a rule, remembering some types of words but forgetting others.
Is there a term for this behavior? What are some effective methods for combating it?
*If it's relevant, the L2 in question is Japanese.
