* Girl: The "r" sound is pronounced, making it sound like "gurr-l."
* Gal: The "l" sound is silent, making it sound like "gal."
So, while "gal" can be used as a slang term for "girl," it doesn't quite have the same pronunciation.
However, in casual speech, the pronunciation of "girl" can be more relaxed and might sound closer to "gal" with the "r" sound being less distinct.
