Resembling heat in quality, intensity, or effect; having the appearance or character of heat.
From 'heat' plus the suffix '-like' (Old English 'lic' meaning body or form, evolving to mean 'similar to'). The '-like' suffix allows quick comparison without using 'as' or 'than' constructions.
The '-like' suffix lets us describe things poetically—'heatlike passion' or 'heatlike glow'—by comparing metaphorically without stating 'like heat' outright. It's why we have 'dreamlike,' 'lifelike,' and 'warlike,' all compressing similes into single words.
