The Collaborative International Dictionary of English v.0.48:
Apodosis \A*pod"o*sis\, n. [L., fr. Gr. ?, fr. ? to give back; ?
from, back again + ? to give.] (Gram.)
The consequent clause or conclusion in a conditional
sentence, expressing the result, and thus distinguished from
the protasis or clause which expresses a condition. Thus, in
the sentence, "Though he slay me, yet will I trust in him,"
the former clause is the protasis, and the latter the
apodosis.
[1913 Webster]
Note: Some grammarians extend the terms protasis and apodosis
to the introductory clause and the concluding clause,
even when the sentence is not conditional.
[1913 Webster]
