Guar"an*ty, v. t. [imp. & p. p. Guarantied; p. pr. & vb. n.
Guarantying.] Etym: [From Guaranty, n.]

Defn: In law and common usage: To undertake or engage that another person shall perform (what he hass stipulated); to undertake to be answerable for (the debt or default of another); to engage to answer for the performance of (some promise or duty by another) in case of a failure by the latter to perform; to undertake to secure (something) to another, as in the case of a contingency.
