/ˈmɪnɪt/ (time unit) or /maɪˈnjuːt/ (tiny)
[noun] A unit of time equal to sixty seconds, or one sixtieth of an hour. The word can also be used as an adjective meaning extremely small or paying close attention to very small details.
Every minute you track today was once called a 'first small part' — and the second got its name because it was the second time they divided.
The story of 'minute' begins in ancient astronomy, where precise measurement was everything. Medieval scholars working with the texts of Ptolemy and other Greek astronomers needed a way to describe fractions of a degree in a circle. They used the Latin phrase 'pars minuta prima', meaning 'first small part', to describe one sixtieth of a degree. This phrase was the seed from which our modern word would eventually grow.
The key Latin root here is 'minutus', the past participle of the verb 'minuere', meaning 'to lessen' or 'to make smaller'. This verb itself descended from the Proto-Indo-European root '*mei-', carrying the sense of small or lesser. From the same Latin root 'minutus', we get a direct line into English: Latin 'minutus' → Old French 'minute' → Middle English 'minute', arriving in the language around the 14th century. The word carried its original mathematical meaning — a sixtieth of something — before it settled into referring to time specifically.
The connection to time came through the same astronomical tradition. Just as a degree of arc could be divided into sixty 'minutae primae' (first small parts), an hour could also be divided into sixty such parts. When clockmakers and scholars began talking about divisions of the hour, they borrowed the same vocabulary. By the late 14th and early 15th centuries, 'minute' had firmly attached itself to the idea of sixty seconds of clock time, a meaning we have carried unchanged ever since.
The adjective form of the word — meaning 'very tiny' or 'paying attention to the smallest details' — follows a slightly different pronunciation (/maɪˈnjuːt/) but shares the exact same Latin ancestor. When we say a scientist made a 'minute observation', we are using the word almost in its original Latin sense: something small, reduced, made lesser. This double life of the word — as both a unit of time and a description of smallness — is a beautiful reminder that the two meanings were never truly separate.
The phrase 'pars minuta secunda', meaning 'second small part', gave us the word 'second' for the next subdivision of time. So when you check your watch and read the minutes and seconds, you are reading a Latin sentence written by medieval astronomers: the first small part, and the second small part. Few everyday objects carry such an elegant piece of linguistic history on their face. The word 'minute' also gave English 'minutiae' — the tiny details — via Latin 'minutiae' meaning 'trifles', and influenced words like 'diminish' (Latin 'diminuere' → Old French 'diminuer' → Middle English 'diminishen') and 'minor' (directly from Latin 'minor', the comparative of 'parvus', meaning lesser).
