"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 ollymi, apollymi "destroy." 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]
c. 1300, punishen, "inflict a penalty on," from Old French puniss-, extended present-participle stem of punir "to punish," from Latin punire "punish, correct, chastise; take vengeance for; inflict a penalty on, cause pain for some offense," earlier poenire, from poena "penalty, punishment" (see penal). Colloquial meaning "to inflict heavy damage or loss" is recorded from 1801, originally in pugilism. Related: Punished; punishing.
The form in English was altered 16c. by influence of base (adj.), making the word an exception to the rule that Old French verbs with stem -iss- enter English as -ish (comprehension might have played a role; earlier forms of abase often are identical with those of abash). Literal sense of "lower, depress" (late 15c.) is archaic or obsolete. Related: Abased; abasing.
