era
era, age
noun EH-rah Rare
Origin: From Latin 'aera' (a fixed point in time, epoch), possibly from 'aes/aeris' (bronze, money — referring to a reckoning date).
Usage Note
Era as a noun means a historical age or era. It is also, identically spelled, the imperfect tense form of ser ('was/were'), so era una era oscura is technically ambiguous on paper — context always disambiguates. The word época is a close synonym for historical period but era implies a longer, more defined geological or historical span.
Examples
"Vivimos en la era digital."
Natural Translation
We live in the digital era.
