- nounSomething that is number two in a series.
- verbTo agree as a second person to (a proposal), usually to reach a necessary quorum of two. (See under #Etymology 3 for translations.)
The second is a unit of time derived from the division of the day, first into 24 hours, then into 60 minutes, and lastly into 60 seconds, for a total of 24 × 60 × 60 = 86400 seconds per day.
