Who said ” I Came, I Saw, I Conquered ?

The original and usual meaning of nick is, broadly, ‘a small notch, groove, chip, or the like’; these senses may be defined in ever more narrow ways, but we’re still dealing with the same concept.

The phrase the nick of time is part of a group of figurative uses having the broad meaning ‘precise; exact’. The earliest use in this family is the (very) nick, which, like nick of time, means ‘at the precise or exact moment required; the critical moment’. Some other senses, all obsolete, are ‘the exact point aimed at; the mark’; ‘the precise moment in time (of something that has already occurred)’, as in “The lovers were surprised in the nick of escaping”; and ‘a point; degree’. There are some similar verb definitions, including ‘to correspond to; tally; suit exactly’ and ‘to hit the mark; guess exactly’.

These meanings stem from the sense of a nick as something very precisely defined; a nick is not a large hole, or a scrape, or anything else that is diffuse; it is a small, sharp, indentation whose exact location is clear.

Nick meaning ‘the precise moment’ is first found in the 1570s and was said to have been common by the late sixteenth century; nick of time itself is recorded from the middle of the seventeenth centuy. The literal use of nick ‘a small notch’ is found in the late fifteenth century. The ultimate origin of this nick is uncertain.”

In Latin, its ‘Veni Vidi Vici.’
