1. To reach it’s the highest altitude – Mariam Webster dictionary
2. To rise to or form a summit
3.to reach the highest or a climactic or decisive point
This word was found in an essay called “The Tool”.
The sentence which shows how the word was used says, “Have you ever thought, not only about the airplane but about whatever man builds, that all of man’s industrial efforts, all his computations, and calculations, all the nights spent over working draughts and blueprints, invariably culminate in the production of a thing whose sole and guiding principle is the ultimate principle of simplicity?”
When I think of the word Culminate, I think of the word climax. To culminate is to reach the highest point.
