Quiz: Remember the definition of mal de mer?
Old English æfter "after, next, throughout, following in time, later," from Old English of "off" (see of) + -ter, a comparative suffix; thus the original meaning was "more away, farther off." Cf. Old Norse eptir "after," Old High German aftar, Gothic aftra "behind." Cognate with Greek apotero "farther off."
After hours "after regular working hours" is from 1861. Afterwit "wisdom that comes too late" is attested from c.1500 but seems to have fallen from use, despite being more needed now than ever. After you as an expression in yielding precedence is recorded by 1650.
Old English eall "all, every, entire," from Proto-Germanic *alnaz (cf. Old Frisian, Old High German al, Old Norse allr, Gothic alls), with no certain connection outside Germanic.
Combinations with all meaning "wholly, without limit" were common in Old English (e.g. eall-halig "all-holy," eall-mihtig "all-mighty") and the method continued to form new compound words throughout the history of English. First record of all out "to one's full powers" is 1880. All-terrain vehicle first recorded 1968. All clear as a signal of "no danger" is recorded from 1902. All right, indicative of approval, is attested from 1953.
