-less

Etymology

It is inherited from Middle English -les, also -lesse,^[2][3][1] inherited from Old English -lēas,^[4][2][3][5] the combining use of lēas (“devoid of, free from; false”),^[2][6][7] from Proto-Germanic *lausaz (“loose”).^[6][1][3] Etymonline takes that from Proto-Indo-European *leu- (“to loosen, divide, cut apart”),^[6] and Barnhart reconstructs Proto-Indo-European *lou-so-s.^[3] It is cognate with Old Frisian -lās, Dutch -loos, German -los, Old Norse -lauss, Swedish -lös, Danish -løs and Gothic 𐌻𐌰𐌿𐍃 (laus, “empty”).^[4][6][2] It is related to loose, lose, loss and the adjective lease,^[5][4][6] but not to less,^[1] although the OED thinks the shortened vowel and the spellings -lesse and -less encouraged an association with that word.^[4]

Earliest recorded meaning

As an independent adjective in Old English, lēas took a genitive of the thing lacked, as in firena lēas, free from crimes.^[5][4] More often it was the second part of a compound with a noun, meaning without, free from or bereft of: wīflēas (“wifeless”), blōdlēas (“bloodless”).^[5][4]

Semantic evolution

The independent adjective did not survive in this sense into Middle English, which left the form to be felt as a suffix.^[4] Some Old English nouns in these compounds were also nouns of action, so the result could mean "not to be counted" as well as "having no count", as in countless and numberless.^[5][4] By analogy, the suffix was then added to verbs, giving tireless and dauntless.^[5][4] Adjectives in -less sometimes pair as opposites with those in -ful, a suffix with a similar early history.^[4]

Timeline
