I assume 雪茄 (cigar) is a loanword. Who can tell me what language this word was loaned from and, if appropriate, how it was transcribed?
My own guess is that the word was transcribed from English and entered the Chinese lexicon via Cantonese - in which case the pronunciation of the characters may actually be similar to the English pronunciation of the word "cigar". This is just my guess though and I have no idea whether it's on the mark of completely off.
