Synonym discussion
Sense: adverb/1
These four adverbs describe emotional distance, but with different tones. 'Coldly' is the most neutral and common — it describes a general lack of warmth in behaviour ('She coldly informed him that his contract was cancelled.'). 'Icily' adds sharpness: the person's manner feels cutting, like a cold wind ('He icily dismissed every suggestion she made.'). 'Coolly' has two very different readings: it can mean 'calmly under pressure' (positive) or 'in a slightly distant way' (neutral to mildly negative). 'Frigidly' is the strongest and rarest; it usually suggests a personal, almost sexual coldness and carries a formal tone ('The couple sat frigidly apart during the dinner.'). For most everyday situations, 'coldly' is the safest and most frequent choice.
Etymology
Formed in Middle English from the adjective 'cold' (from Old English 'ceald', meaning 'having a low temperature') plus the adverbial suffix '-ly' (from Old English '-lice'). The emotional sense of 'cold' — meaning 'unfriendly or lacking feeling' — dates back to at least the 1300s, and 'coldly' followed as its adverb shortly afterward.
