Frequently Asked Questions

Is swapping "ses" for "sus" ever safe?
No - they are not even the same part of speech. "ses" is an article and "sus" an intj, so a sentence built for one is usually ungrammatical with the other.
In ordinary Spanish text, does "ses" or "sus" show up more?
"sus" is the more common of the two: it sits at frequency rank #32 in our Spanish list, against #27,012 for "ses". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
