漢：形容詞后綴less意為“without”，表示否定意義的-less是個(gè)本族語(yǔ)派生后綴，原意為free from 或without。它主要加在名詞后面，構(gòu)成相應(yīng)的形容詞，意為without（無(wú)...的），lacking(缺乏...的），free from（沒(méi)有...的）等；它也可以與某些動(dòng)詞結(jié)合，意為that never ～s（從不...的），that cannot be ～ed（不可...的）。


英：word-forming element meaning "lacking, cannot be, does not," from O.E. -leas, from leas "free (from), devoid (of), false, feigned," from P.Gmc. *lausaz (cf. Du. -loos, Ger. -los "-less," O.N. lauss "loose, free, vacant, dissolute," M.Du. los, Ger. los "loose, free," Goth. laus "empty, vain"). Related to loose and lease.
