[Used] in reference to I am slow [sc. to do something].[1] And [used] in in reference to future time in Thucydides.[2]
And Sophocles [writes]: "for always putting off doing something I have destroyed my present and absent hopes."[3]
And Aristophanes [writes]: "I beg you not, except when I am about to vomit." That is, if you say [it] in full, "Say [it] then, when I am about to vomit" -- so that I may vomit [it] up once and for all, and not both then and when you say [it]. Or thus: "say [it] then, if you wish, watching out for when I am about to vomit; for I would vomit [it] up most easily if you say [it]."[4]
