firewood

This term refers specifically to wood that has been processed for combustion. It carries a connotation of rustic self-sufficiency and preparation, often evoking images of winter, hearths, and outdoor survival.

Grammatically, this noun is uncountable. It describes a mass of material rather than individual pieces; therefore, it cannot be pluralized as firewoods. To refer to individual units, one must use partitive constructions such as a log of firewood or a stack of firewood.
