Morphology

limit + point

The phrase is compositionally a point characterized by being a limit: with 'limit' meaning the value approached and 'point' meaning a specific position, a learner can infer 'a point that a function or sequence approaches.' This follows regular noun–noun compounding and mirrors comparable constructions in other languages, so the meaning is directly derivable from the parts.

Etymology

The term limit point comes from the simple image of a single spot that numbers get closer to. The word limit is about getting near and point is that spot. Imagine walking closer and closer to a door but never touching it; the door is the limit point, so the term means 'a value a function gets close to'.
