Another similar thing is the definition of ripe.

A fruit can be ripe for consumption (culinary ripeness), and it can be ripe for seed-bearing (botanical ripeness). You can see the difference with cucumbers, which are ripe for eating when they are green and the seeds are barely developed, while they are close to inedible when ripe for seed-bearing. Then they will turn yellow, the pulp shrinks down and becomes slimy and the seeds become big and hard.
