What's the difference between i.e. and e.g.?
"capable of being done, accomplished or carried out," mid-15c., from Anglo-French faisible, from Old French faisable "possible, easy, convenient," from fais-, stem of faire "do, make," from Latin facere "do, perform" (see factitious). Fowler recommends this word only for those "who feel that the use of an ordinary word for an ordinary notion does not do justice to their vocabulary or sufficiently exhibit their cultivation."
