Warm spell
Meaning
A period of unusually warm weather that lasts for a short time.
Origin
The term "warm spell" is wonderfully literal, but its nuance comes from the word "spell" itself. Originating from the Old English 'spelian,' meaning "to take the place of" or "to continue," this sense of "spell" evolved to denote a distinct, often brief, period of time during which a particular condition prevails. It's a temporary replacement, a short duration. So, a "warm spell" is precisely that: a brief period of warmth that temporarily replaces the more typical weather conditions. It's not a complex idiom, but rather a direct and evocative description that gained popularity as people began to more precisely categorize and discuss meteorological phenomena, especially from the 19th century onwards when weather observation became more systematized.
Examples
