Etymology

It is inherited from Middle English likli, probably borrowed from Old Norse líkligr (“likely”) (also glíkligr),[2][3][4][5] formed from líkr (“like”) and -ligr (“-ly”).[4][6] Old English had the cognate gelīclīc (“fitting”),[2][3][7] from which Barnhart and Merriam-Webster also derive it.[3][8] It is related to like and likelihood.[9]

Earliest recorded meaning

Probable, likely to happen, as a predicate with an infinitive: before 1300;[10] Etymonline gives “having the appearance of truth” from about 1300,[2] and Barnhart's first example is before 1325, in Cursor Mundi.[3]

Semantic evolution

“Probable” is from the late 14th century,[2][10] and the OED notes that it is now chiefly American.[2] “Apparently suitable or qualified” is from about 1375,[10] and of young people “promising” from 1454, now chiefly American.[10][2] “Good-looking”, perhaps influenced by like, “to please”, is from the late 15th century.[2][10] “Resembling, similar” is recorded about 1400.[10] The adverb, “probably”, is from the late 14th century.[2][3] Bartlett's Dictionary of Americanisms gives the colloquial American sense “respectable, worthy of esteem”.[2]
