* "Pas" means "not"
* "Ma" means "my"
To understand the meaning, we need the rest of the phrase. For example:
* "Pas ma faute" means "It's not my fault."
* "Pas ma tasse de thé" means "Not my cup of tea" (meaning something I don't like or am not interested in).
* "Pas ma journée" means "Not my day" (meaning a bad day).
Please provide the full phrase or more context, and I can help you understand its meaning.
