purlinn.

Brit.

/ˈpəːlɪn/, U.S.

/ˈpərlən/

Forms:

α. late Middle English–1600s purloyn, late Middle English–1600s purloyne, 1600s– purloin.

β. late Middle English purlyn, late Middle English purlyon, 1500s purlyne, 1600s pourline, 1600s purlain, 1600s purlinge, 1600s– purlin, 1600s– purline, 1800s perling, 1800s purling.

Origin: Of uncertain origin. Perhaps a borrowing from French. Etymon: French *purloigne.

Etymology: Origin uncertain. Perhaps < an (apparently unrecorded) Anglo-Norman noun *purloigne in sense ‘extension’ (compare Old French porloigne , pourloigne delay, postponement (end of the 12th cent.); the sense in building is apparently not paralleled in French) < purloignier purloin v. Conversion from the English verb seems unlikely, as it is apparently only attested in semantically unrelated senses. Compare post-classical Latin perlio purlin (1448 in a British source); the relationship between this and the English word is unclear. The β forms probably show reduction of the unstressed vowel in the second syllable.

Building.

A horizontal beam which runs along the length of a roof, resting upon the principal rafters at right angles and supporting the ordinary rafters or boards of the roof.
