The DMF suggests the etymon for this
word may be parare (FEW 7,623b, no attestations) but it seems most likely that it represents an aphetic form
derived from *appariculare (e.g. reparaillement)
(
c.1240; MS: s.xiii3/4
)
si aveint que aprés le parraillement del test malvaise char surcresse le test reparrallié, si metez seurement la pudre des hermodacles
