Frequently Asked Questions

Is swapping "det" for "dos" ever safe?
No - they are not even the same part of speech. "det" is a pronoun and "dos" a num, so a sentence built for one is usually ungrammatical with the other.
In ordinary Spanish text, does "det" or "dos" show up more?
"dos" is the more common of the two: it sits at frequency rank #57 in our Spanish list, against #35,459 for "det". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
