The puzzle is different from the ones I usually post in this column. In addition to deductive logic and pattern-spotting, you’ll need some basic intuition about languages.
Beware: it’s hard. But not impossible. The question is taken from the North American Computational Linguistics Olympiad, a competition for high school students.

Grauniad. I didn’t even attempt it and held off posting it till the answer was made available here.
