Brit.

/eɪˈɡastrɪk/, U.S.

/eɪˈɡæstrɪk/

Origin: Formed within English, by derivation; probably modelled on a French lexical item. Etymons: a- prefix⁶, gastric adj.

Etymology: < a- prefix⁶ + gastric adj., probably after French agastrique (1809 or earlier as adjective, 1810 or earlier as noun). Compare scientific Latin Agastrica, former division name (1825 or earlier).

Zoology. Now rare.

Lacking, or apparently lacking, a stomach or an alimentary canal; characterized by this.
