Frequently Asked Questions

Is swapping "uch" for "und" ever safe?
No - they are not even the same part of speech. "uch" is a num and "und" a conjunction, so a sentence built for one is usually ungrammatical with the other.
In ordinary German text, does "uch" or "und" show up more?
"und" is the more common of the two: it sits at frequency rank #3 in our German list, against #45,635 for "uch". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
