/əbˈstrɪkt/

Etymology: < ab- prefix + classical Latin strict-, past participial stem of stringere to bind (see stringent adj.), perhaps after abstriction n.

Biology (chiefly Mycology).

1. transitive. To detach or separate by constriction of a part; to produce or release by abstriction (abstriction n. 2). Usually in passive.

2. intransitive. To split off (from), esp. by constriction of a part.
