At last

The “ae” sound in American English is used in some common words that are pronounced with an “ah” sound in British English, such as “last”. The “ae” sound is the sound in the word “cat” and is made with the corners of the lips pulled back towards the ears, as if smiling. The expression “at last” means “finally” or “after a long wait” (e.g., At last, I made it home.)
