inconceivably

Inconceivably is an adverb in English that denotes that something is beyond belief or beyond what can be imagined. It is used to describe actions, properties, or degrees that are extremely improbable, extraordinary, or difficult to comprehend.

Etymology: The word is formed from the adjective inconceivable with the suffix -ly. The base inconceivable derives from the Latin concipere via Old French; the adverbial form inconceivably has been part of English since the late 18th or early 19th century.

Usage: In writing, inconceivably often modifies adjectives and verbs, as in inconceivably expensive or inconceivably fast. It is common in descriptive or emphatic contexts and can be perceived as hyperbolic or dramatic. In everyday speech, many contexts favor more neutral alternatives such as unimaginably or extraordinarily.

Style notes: The adverb emphasizes scale or extremity rather than a precise measure, and its impact depends on context. Overuse or an dated literary tone can make it feel cliché in some contexts, particularly in humorous dialogue or casual writing.

Related terms: Related forms include inconceivable and inconceivability; it is closely linked to synonyms such as unimaginable, incredible, and extraordinary.
