Frequently Asked Questions

Is swapping "else" for "eso" ever safe?
No - they are not even the same part of speech. "else" is an adjective and "eso" a pronoun, so a sentence built for one is usually ungrammatical with the other.
In ordinary Spanish text, does "else" or "eso" show up more?
"eso" is the more common of the two: it sits at frequency rank #50 in our Spanish list, against #36,015 for "else". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
