Frequently Asked Questions

Is swapping "era" for "et" ever safe?

No - they are not even the same part of speech. "era" is a noun and "et" a conjunction, so a sentence built for one is usually ungrammatical with the other.

In ordinary Spanish text, does "era" or "et" show up more?

"era" is the more common of the two: it sits at frequency rank #65 in our Spanish list, against #2,449 for "et". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
