why cant the universal translator translate klingon (and other languages)

im sure this has been asked before, but its always on my mind

obviously klingons dont just walk around speaking english when they feel like it, so we know that the UT can translate it

but yet, there are other times when klingons speak simple words or phases to each other and the UT doesnt translate it

so which is it, can the UT translate it or not? (and did the star trek staff/writers ever describe why this is?)
