Linguistic Note on Integral Calculus

The term integral calculus is the Anglified version of the neo-Latin phrase calculus integralis, made popular by Gottfried Wilhelm von Leibniz.

At first he suggested calculus summatorius, but in $1696$ he decided with Johann Bernoulli that calculus integralis would be better.

Some sources suggest that the name integral, first used by him in $1690$, may well have been coined by Jacob Bernoulli.
