/ˈbɑːtəmləs/
“Bottomless” means having no bottom, or seemingly without limit or end. It can be used to describe physical things that appear to have no depth, like a “bottomless pit” which seems to have an unending depth. Figuratively, it can describe things like a “bottomless supply” where the amount available seems limitless, or a “bottomless appetite” indicating an insatiable desire for food or other things.
