Etymology
From earlier sentrie, sentery, of uncertain origin. Perhaps an alteration of sentinel or sanctuary; or perhaps from Old French senteret (“a path”), diminutive of sentier, from Medieval Latin semitarius (“a path”).
Webster’s 1913
Etymology [Probably from OF. senteret a little patch; cf. F. sentier path, and OF. sente. See Sentinel.]
