* "Au" usually makes the "aw" sound: Like in "caught," "taught," "fault," "daughter," etc.
* "Au" can also make the "oh" sound: Like in "author," "fraud," "launch," "gauche," etc.
There are a few exceptions, mostly in proper nouns:
* "Aunt" - The "au" makes the short "a" sound.
* "Gauntlet" - This word has a more complex sound where "au" is closer to a short "a" sound than "aw."
