comparative form of warm: more warm
"The soup tastes much warmer than the coffee I had earlier."
In plain English: Warmer describes something that is more heated than before.
"The sweater felt much warmer than my old jacket on this chilly morning."
Usage: Use the irregular superlative "warmest" rather than the grammatically incorrect "warmerest." In most contexts where comparison is needed, prefer the standard adjective "warmer" over the noun phrase "a warmer," which refers specifically to a heating device.
Warmer is formed by adding the suffix "-er" to the word "warm." This construction simply indicates a thing or person that possesses more warmth than usual.
