balmy

the word 'balmy' traces its lineage to the ancient concept of a healing aromatic substance. its core, 'balm', entered english via latin and greek from a semitic source, referring to the resin of the balsam tree, prized for its soothing and fragrant properties. by the 15th century, the adjective 'balmy' was formed, initially describing things having the qualities of balm, such as being fragrant or soothing. the modern primary meaning, describing pleasantly mild weather, is a metaphorical extension from this sense of soothing comfort. the informal, now dated meaning of 'crazy' (as in 'balmy on the crumpet') is a 19th-century british slang development, likely originating from a rhyming slang play on 'barmy' (frothy, fermenting, and thus figuratively flighty or excited), with the two spellings becoming conflated.

the word is a simplex form. it is derived from the english word 'balm' (an aromatic oily resin from certain trees, used for healing and soothing) with the addition of the adjectival suffix '-y'. 'balm' itself originates from latin 'balsamum', from greek 'balsamon', likely of semitic origin.
