Word origin
From Latin abstractus, past participle of abstrahere ('to draw away'), formed from abs- ('away from') + trahere ('to draw, pull'). Both verb and adjective senses descend from the same Latin source; the pronunciation difference is purely a stress-shift phenomenon in modern English, with end-stress on the verb and front-stress on the adjective and noun.
Fun fact
The verb-versus-adjective stress shift in 'abstract' is part of a productive English pattern called the trochaic noun rule, which gives verbs end-stress and corresponding nouns or adjectives front-stress — the same pattern produces 'record/record', 'present/present', 'conduct/conduct', and dozens of others.
