lag behind

crawl creep hang shuffle

dally dawdle delay inch lag linger loiter poke procrastinate sag shamble stagnate straggle tarry traipse

be delayed be quiescent encounter difficulty limp along mark time put off slow down trail behind

advance finish go hasten hurry push run rush speed

drop back drop behind hang fire hang off hold back hold off hover pause procrastinate shrink back shy away stay back stick straggle trail

forge ahead
