respirableadj.

Brit.

/ˈrɛsp(ᵻ)rəbl/,

/rᵻˈspʌɪrəbl/, U.S.

/ˈrɛspərəb(ə)l/

Origin: Formed within English, by derivation. Etymons: respire v., -able suffix.

Etymology: < respire v. + -able suffix. Compare post-classical Latin respirabilis (6th cent. in Boethius), French respirable that breathes (1380), suitable or fit for breathing (15th cent., earliest of the mouth and nose; 16th cent. of air).

a. Of air or a gas: able or fit to be breathed; suitable for respiration, spec. containing sufficient oxygen to sustain life. In later use also (of particles, fibres, etc., suspended in air): inhalable; capable of reaching the lungs.

b. Biology. Originally: capable of acting as a source of energy, or of forming fat. In later use: spec. that is a substrate for the metabolic process of respiration.

1901 Amer. Naturalist 35 475 The enzymes formed by lower plants are also useful in more than one way, not the least important use being the conversion of irrespirable into respirable substances.

1946 A. Nelson Princ. Agric. Bot. xvii. 347 The ratio between the two quantities depends on the nature of the compounds used by the plant as the source (respirable substrate) of the energy released.
