Etymology

Origin of almighty

before 900; Middle English; Old English ælmihtig, ealmihtig, equivalent to æl-, eal- all (cognate with Old Norse al- < *ol-o- ) + mihtig ( miht, meaht might ² + -ig -y ¹ ); cf. Alemanni

Explanation

Anything that's almighty is extremely powerful. In fact, being almighty gives something (or someone) an infinite amount of power. Originally, the adjective almighty was capitalized and used to refer to God. It comes from the Old English ælmihtig, "all-powerful." You could also describe something that's almighty as "omnipotent" or even "godlike." Today people often use almighty in a sarcastic or ironic way to talk about things that exert a ridiculously huge amount of control over people: "All he cares about is the almighty dollar."
