Frequently Asked Questions

Can "m" and "MRT" be used interchangeably?

No - they are not even the same part of speech. "m" is a character and "MRT" an abbrev, so a sentence built for one is usually ungrammatical with the other.

In ordinary German text, does "m" or "MRT" show up more?

"m" is the more common of the two: it sits at frequency rank #231 in our German list, against #20,350 for "MRT". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
