Mightily

Mightily is an adverb that conveys action performed with great power, effort, or intensity. It describes the manner of an action, often emphasizing physical strength, force, or determined energy. The term can also imply substantial progress or impact achieved through strenuous effort.

Etymology: The word is formed from the noun might, meaning power or strength, plus the adverbial suffix -ily. It appears in Old and Middle English and has continued into Modern English, though its everyday use is now more literary or formal.

Usage and register: Mightily is most common in historical, biblical, or elevated prose. In contemporary speech, speakers usually replace it with phrases such as 'greatly,' 'very,' or 'with great effort.' It is frequently used with verbs of action, such as fight, press, pray, or argue.

Examples: "The army pressed on mightily against the fortifications." "She argued mightily for reform." "The wind blew mightily that night."

See also: might, mighty. Notes: The adverb should not be confused with 'mightly' which is rarely used and considered incorrect in standard English. Antonyms include weakly or feebly.
