So we are both cautious :) If you mean Aztec imported words, I don't know which they are. Maybe you mean the tl consonant group that is not very natural, but neither is zr (as in three) and we just get used to it, when we learn English. Could "chocolate" be one of these words? It was just adapted, both pronuntiation and spelling. The problem now is imported. It seems English has no letter for j sound... ahem, the real j sound :) being the h (as in hot) the closest, but way weaker, so when transcribing from other alphabets, like Arabian or Cyrilic, it's written as kh, see Ха́рків. But the trick isn't working and everybody reads it as a lone k. Also we receive the kh transcription... what a mess :)
