septifragaladj.

Brit.

/sɛpˈtɪfrəɡl/, U.S.

/sɛpˈtɪfrəɡ(ə)l/

Forms: 1800s–1900s septafragal (irregular), 1800s– septifragal.

Origin: A borrowing from Latin, combined with English elements; modelled on a French lexical item. Etymons: septi- comb. form², Latin frag- , frangere , -al suffix¹.

Etymology: < septi- comb. form² + classical Latin frag-, stem of frangere to break (see fragment n.) + -al suffix¹, after French septifrage (1808 in the passage translated in quot. 1819).Compare post-classical Latin septifragus (1816 or earlier).

Botany.

Designating a type of dehiscence in which the valves of a capsule break away from the septa. Also (of a fruit, esp. a capsule): that dehisces in this manner.
