blue

I. blue, a.
    (bluː, bljuː)
    Forms: 3 bleu, 3–8 blew, 4 blu(e, bluw(e, 4–5 blwe, 4–6 blewe, 7– blue.
    [ME. blew, a. OF. bleu, a Common Romanic word (= Pr. blau, blava, OSp. blavo, It. dial. biavo, med.L. blāvus), ad. OHG. or OLG. blâw-:—OTeut. blæ̂wo-z blue, whence also ON. blá-, likewise adopted in ME. as bla, blo, now blae. The corresponding OE. form bláw (or *blǽw) is known only in Erfurt Gloss. 1152, ‘blata, pigmentum: haui-blauum’, and the derivative blǽwen (:—blâwîno-) ‘perseus’. But neither of these survived into ME., where their place was supplied by the adoption of ON. blá, in sense of ‘lividus’, and of F. bleu in sense of ‘cæruleus’. The OTeut. blæ̂wo- was perh. cognate with L. flāvus yellow (though blôwo-z would be the expected Teutonic form), the names of colours having often undergone change in their application; thus OSp. blavo was ‘yellowish-grey’. (The guess that blæ̂wo- was derived from the stem *bliuwan, Goth. bliggwan to beat, as ‘the colour caused by a blow’ is not tenable.) The present spelling blue is very rare in ME., and hardly known in 16–17th c.; it became common under French influence only after 1700. In pronunciation, nearly all the dictionaries c 1887 still recognized (bljuː), but the more easily pronounced (bluː) was already general in educated speech.]
