CLerpNodePathInterval - a query

What is the meaning of lerp in this context ?

CLerpNodePathInterval Class Reference -

An interval that lerps one or more properties (like pos, hpr, etc.) on a NodePath over time.

Can anybody the concept behind this class in plain english ?

Hi, the documentation of its parent doesn’t contain that contraction:

I presume the class you have cited does this on a specific NodePath.

Yes you are right. I should have got the idea myself.
