testern.¹

Brit.

/ˈtɛstə/, U.S.

/ˈtɛstər/

Forms: α. Middle English– tester; Middle English testere, testour, testir, testur(e, testre, Scottish tyster, tystyr, Middle English–1500s teester, 1500s (1800s) testor, 1500s–1600s testar, teaster (1800s dialect), 1600s taister. β. 1500s testerne, teasterne, testorne, 1600s testarn, testern.

Etymology: probably < Old French: compare testre (feminine) (15th cent., one example in Godefroy) the vertical part of a bed behind the head; also Old French testière , modern French têtière a covering for the head, etc., Italian testiera , Spanish testera , medieval Latin testera , -eria (see tester n.²); also medieval Latin testerium, testrum, testūra, also testāle, all, according to Du Cange, = ‘the upper part, top, or upper covering of a bed’, derivatives of Latin testa, in late popular Latin and Common Romanic ‘head’. The historical relations of these words are not quite clear, but apparently medieval Latin testerium, -eria, Italian testiera, Spanish testera, Old French testière, and Middle English testere, go together in form, as do medieval Latin testrum, Old French and Middle English testre, and perhaps also medieval Latin testura and Middle English testur; though the senses are specialized in different languages. The other English forms appear to have been assimilated to various endings in -er, -ar, -or, -our, and (erratically) -ern, -orn.

1. A canopy over a bed, supported on the posts of the bedstead or suspended from the ceiling; formerly (esp. in phrase tester and celure), the vertical part at the head of the bed which ascends to and sometimes supports the canopy, or (as some think) the wooden or metal framework supporting the canopy and curtains.
