Frequently Asked Questions

Is swapping "em" for "ese" ever safe?

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

In ordinary Spanish text, does "em" or "ese" show up more?

"ese" is the more common of the two: it sits at frequency rank #84 in our Spanish list, against #7,152 for "em". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
