Realize that many verbs can be both transitive and intransitive. An action verb with a direct object is transitive while an action verb with no direct object is intransitive. Some verbs, such as arrive, go, lie, sneeze, sit, and die, are always intransitive; it is impossible for a direct object to follow.
For example, get up is a phrasal verb made up of the simple verb get and the word up, which is usually considered to be a particle but sometimes an adverb. Note that there is no intuitive connection between the meanings of get and get up.. Spanish has no equivalent of phrasal verbs. But it is important to understand how they work when translating them to Spanish; the two (or sometimes three) components of the phrasal verb cannot be translated separately.
