I’ve been waiting for several weeks to tackle this word, hoping that it wouldn’t be necessary. But it looks as if the inactivity of Congress on the matter of finance is going to make sequestration a reality, so let’s take a look at the word. Check out this historical piece from Online Etymology Dictionary.
Sequester: late 14c., from O.Fr. sequestrer (14c.), from L.L. sequestrare “to place in safekeeping,” from L. sequester “trustee, mediator,” probably originally “follower,” related to sequi “to follow” (see sequel). Meaning “seize by authority, confiscate” is first attested 1510s.
