derring-do

derring do, derring-do pseudo-archaism.
  In 4–5 dorryng, (dorynge, duryng) don (do, to do), 5 doryng(e do, 6 derrynge do, derring doe, 9 derring-do.
  The two words durring, dorryng, daring, vbl. n. from durran, dorren to dare, and don, do, pres. inf. of do v., literally daring to do, which, by a chain of misunderstandings and errors, have come to be treated as a kind of substantive combination, taken to mean, Daring action or feats, ‘desperate courage’.
  The words come incidentally in their ordinary sense and construction followed by the object ‘that’ (= what, that which) in Chaucer's Troylus; whence, in an imitative passage by Lydgate, in an absolute construction more liable to misunderstanding; Lydgate's dorryng do was misprinted in the 16th c. editions (1513 and 1555) derrynge do, in which form it was picked up by Spenser and misconstrued as a subst. phrase, explained in the Glossary to the Sheph. Cal. as ‘manhood and chevalrie’. Modern romantic writers, led by Sir W. Scott, have taken it from Spenser, printed it derring-do, and accentuated the erroneous use.
