Pronunciation: im/in prefix
How do you pronounce the letters “im” or “in” when they occur at the start of a word in French? Are they nasal or not?
As you can see in the two tables below, the rules are simple. “im” or “in” plus a consonant are nasal. But “imm,” “inn,” “im + vowel,” or “in + vowel” are all oral, which means not nasal.
