Did you know?

Utmost, which typically communicates that something is of the greatest or highest in degree, number, or amount, is commonly found modifying words like importance, concern, and respect. But utmost can also indicate that something is, literally or figuratively, farthest or most distant—that it is outmost, as in “the utmost point.” Utmost in fact traces back to the Old English word ūtmest, a superlative adjective formed from the adverb ūt, meaning “out.” Utmost can also function as a noun referring to the highest attainable point or degree, as in “the inn provides the utmost in comfort and luxury.” The noun also often occurs in phrases such as “we did our utmost to help” where it means “the highest, greatest, or best of one’s abilities, powers, and resources.”
