Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
hālĭto, āre, v. freq. a. [halo], to breathe out: flammam halitantes, Enn. ap. Diom. p. 336 P. (Trag. v. 217 Vahl.).
So perh. also: Scio spiritum ejus majorem esse multo quam folles taurini halitant, Plaut. Fragm. Bacch.; cf. Ritschl in Rhein. Mus. 1846, p. 580.
