Here are some loan-words written with the nasalized vowel   n\/ m\ /  M [an].

READING

You will read the word mn\;tel; as [màn tá lè] when you are reading as it is written, but it is sometimes read or said [màn dâ lè] and sometimes [màn nâ lè].  Notice that the consonant [t] that follows immediately after the nasalized vowel [an] changes to the nasalized consonant [n].  Nasalization of the consonant following after a nasalized vowel usually occurs when a speaker says a word fast.
