n., v. (vbl. n.)
(1) (forlancyng) ‘throwing out’ (pres. ptcp.); (2) (laucyng) ‘loosening’ (vbl. n.)(Modern English (1) lance; (2) loosing)
The only argument against ON derivation rests on an alternative reading of the MS (‘Lystily for laucyng þe lere of þe knot’): (1) MS <for laucyng> is read forlancyng by Madden (followed by Morris, TG etc. and OED) and explained as a prefixed form of ME lancen, launcen 'to throw' < AN, OFr lancer, lancier (< Lat lanceāre); cp. Fr forlancer 'to drive an animal from its lair'. (2) An ME v. forlancen would be unique, however, and most recent editors have followed GDS (1334n) in preferring to read <laucyng>, a vbl. n. on lausen, the v. formed on the adj. ME laus, lōs etc., derived from ON (cp. OIcel lauss 'loose, free (etc.)').

(1) forlance is not recorded as a v. elsewhere by MED or OED. The uncompounded launcen is fairly widespread in ME from c1330(?c1300) Guy(1) (Auch) onwards. (2) The vbl. n. lōsing(e) is recorded by MED from a variety of 14c. and 15c. texts (predominantly in medical contexts). The v. ME lōsen is widespread from early ME; see further lausen.
