1. lag behind sb. 落后于某人。
3. or from some dialectal version of last, lack, or delay.
- lag: English has three distinct words lag. The verb ‘fall behind’  is perhaps of Scandinavian origin (Norwegian has lagga ‘go slowly’), although a link has been suggested with the lag of fog, seg, lag, a dialect expression used in children’s games which represents an alteration of first, second, last. Lag ‘insulate’  comes from an earlier noun lag ‘barrel stave’, which was also probably borrowed from a Scandinavian language (Swedish has lagg ‘stave’); the original material used for ‘lagging’ was wooden laths.
And finally the noun lag ‘prisoner’  seems to have come from an earlier verb lag, which originally meant ‘steal’, and then ‘catch, imprison’; but no one knows where this came from.
- lag (v.)
- "fail to keep pace," 1520s, earlier as a noun meaning "last person" (1510s), later also as an adjective (1550s, as in lag-mon "last man"), all of uncertain relationship, possibly from a Scandinavian source (compare Norwegian lagga "go slowly"), or some dialectal version of last, lack, or delay. Related: Lag; lagging. The noun meaning "retardation" is from 1855. First record of lag time is from 1951.
