The first word is…Ca va. Ca va can mean how are you doing if you say it in a questioning voice, or it can mean things are fine if you say it as a response. It kind of sounds like this say “sa” like in the beginning of salsa, then say “va” with the same sounding a as in the sound “sa” .
The second word is… Merci. Merci means thankyou and it sounds excactly like the word “mercy” but just with a french accent.
