What does على مهلك mean?

@imanxo براحتك is more like “it’s up to you “ so like if you wanna ask someone like what do you wanna do ?should we go to the park or home ? And he really don’t know he would say u can decide براحتك
————————
If you ask someone for something and they seem to be a little bit distracted no knowing what to start first and wanna do it fast like literally lost and they tell you I will try to finish it soon or something related to time you can say خذ/ي راحتك

For على مهلك it literally means don’t do it fast just do it slowly in a way you feel comfortable like take your time doing it
It can also be used if someone suddenly fell or accidentally hit himself with something they would say على مهلك be careful/don’t move too fast /look carefully around you/ if someone was doing anything too fast and something happened because of his careless you say على مهلك
Like if someone eat fast and he suddenly Choking on food u say على مهلك /شوي شوي
(شوي a little )


راحتك = Your convenience/when you have time and you’re free/
feeling good
?مهل wait /slowly
عجلة quickly
