Navigable is an adjective that means able to be sailed on by ships or boats.
The Latin word navigare (nav uh GAR ay) means ‘to sail.’ From this word, we get the English word ‘navigate’ as well as our word of the day which basically means ‘able to be navigated by boats or ships.’ Here’s an example:
Before the tsunami, nearly all of the port was navigable. But since the storm hit, there’s barely a place that can be sailed on.
