Usage notes
Remaining true to its Indo-European root, the adverb ᾱ̓εί imparts the sense that a verbal action occurs continuously for "a long time" in a variety of specifications, or indeed for all time. When specifying a temporally bounded period of time, ᾱ̓εί may refer to an action occurring: either from the far past through the present, from the present until a distant future, for a relatively long time in either the past or in the future, or from the far past through a distant future. Contrast, which (where not negated) indicates that a verbal action might occur at any time over a long period of time, but not necessarily continuously.
