Questions & Answers about Era un barrio pobre.
Era is the imperfect form of ser (to be), and it usually describes a background situation, an ongoing state, or what something was like in the past.
So Era un barrio pobre suggests something like:
- It was a poor neighbourhood
- describing the area as it used to be
- giving background information
By contrast, fue is the preterite, which often presents the idea as a completed fact or event. In many contexts, era sounds more natural for description.
A very rough contrast:
- Era un barrio pobre. = It was a poor neighbourhood / It used to be a poor neighbourhood
- Fue un barrio pobre. = It was a poor neighbourhood in a more bounded, completed sense
Spanish often leaves out subject pronouns when they are not needed. The verb form itself usually gives enough information.
Here, era can mean:
- he/she/it was
- or you (formal) were, depending on context
In this sentence, the context tells you that it was is the intended meaning. Spanish does not need to say ello era or eso era here.
So:
- Era un barrio pobre is completely natural
- adding a subject pronoun would usually be unnecessary
