"put an end to, do away with," mid-15c., from Old French aboliss-, present-participle stem of abolir "to abolish" (15c.), from Latin abolere "destroy, efface, annihilate; cause to die out, retard the growth of," which is perhaps from ab "off, away from" (see ab-) + the second element of adolere "to grow, magnify" (and formed as an opposite to that word), from PIE *ol-eye-, causative of root *al- (2) "to grow, nourish," and perhaps formed as an antonym to adolere.

But the Latin word rather could be from a root in common with Greek olluein "destroy, maker an end of." Tucker writes that there has been a confusion of forms in Latin, based on similar roots, one meaning "to grow," the other "to destroy." Now generally used of institutions, customs, etc.; application to persons and concrete objects has long been obsolete. Related: Abolished; abolishing.

Abolish is a strong word, and signifies a complete removal, generally but not always by a summary act. It is the word specially used in connection with things that have been long established or deeply rooted, as an institution or a custom : as to abolish slavery or polygamy. [Century Dictionary, 1900]

late 14c., from Old French establiss-, present participle stem of establir "cause to stand still, establish, stipulate, set up, erect, build" (12c., Modern French établir), from Latin stabilire "make stable," from stabilis "stable" (see stable (adj.)). For the unetymological e-, see e-. Related: Established; establishing. An established church or religion is one sanctioned by the state.
