'balminess' originates from English, specifically the adjective 'balmy', where the suffix '-ness' meant 'state or quality'.

'balminess' changed from the adjective 'balmy' (formed from 'balm' + suffix '-y') with the addition of the noun-forming suffix '-ness', and eventually became the modern English noun 'balminess'.

Initially, related to 'balm' and meaning 'having the qualities of balm; soothing or aromatic', but over time it evolved into its current meaning of 'the quality of being pleasantly warm or soothing'.
