What does incombustibly mean?
Incombustibly is an adverb meaning in a manner that cannot be affected by burning or consumed by fire. It is formed from the adjective incombustible, which describes a material or substance that is not liable to ignite, char, or burn under ordinary conditions. The adverb is much less common than the adjective and tends to appear in formal, technical, historical, or occasionally literary contexts. Its wording can sound emphatic, as when a structure or object is described as remaining intact in extreme heat. In most practical and descriptive writing, saying that something is fireproof, nonflammable, or incombustible is more natural than using this adverb. Nevertheless, incombustibly is a precise formation that emphasizes the manner in which something withstands fire without burning.
adverbIn a manner that is incapable of burning; in an incombustible way.
- In an incombustible manner; so as not to burn or be consumed by fire.
"The structure remained incombustibly intact despite the intensity of the fire."
"The coating is intended to keep the underlying material incombustibly stable during extreme heat."
"The building's timbers had been treated so that they remained incombustibly intact in the blaze."
Incombustibly takes an already unusual idea—being unable to burn—and makes it even more unmistakably technical.
