Final in an order, and most recent. Also to endure — the same word for the end and for holding on.
Two Old English words fell together in this one spelling: laetest, the superlative of laet (slow, late), giving final and most recent; and laestan (to follow a track, continue, perform), related to laest (a footprint), giving to endure.
The end of an order and the act of holding on share this one word, so finishing and enduring sound, for a moment, like the same thing.
