What does no lo veo mean in English?

The English equivalent of the Spanish sentence 'No he visto nada' is the following: I didn't see anything. The Word-by-Word translation is the following: 'no' means 'not'; 'he' '[I] have'; 'visto' 'seen'; 'nada' 'nothing'. Spanish speakers aren't required to use subject pronouns.
