It is the point in space where two bodies ( a star, a planet, a moon, asteroid, whatever) balance or have equal gravitational pull.
This means that an object at rest there will not fall into either body, but will "rest" there, being pulled equally in both directions.
It is not the halfway point between them in terms of distance, it is the gravity halfway point.
Kind of like being on a teeter totter with someone half your size. if you sit closer to the middle and they sit farther out, you can still both balance out.

A legrange point is where the gravitational effects of planets or moons or a star all balance each other out. In space since there's no friction, an object like a satelite or proble will be pulled around by the gravity of some big object like that. If you put the satelite at a legrange point, then all the gravities balance out, and the satelite will stay there.
Think about having three magnets and a steel marble. If you put the marble on a table, and the magnet in the middle, it will pull the ball towards it. But if you put 3 magnets in a triangle, and the steel marble in the middle of the triangle, they're all going to pull the same- so the marble wont go anywhere. That's what a legrange point is like.

A Lagrange Point is a location in space where the gravitational pull from 2 or more objects cancel each other out.
Think of the moon and earth. Each exert gravitational pulls on an object between them (a satellite, for example). There is a point such that earth's pull on the satellite is the same magnitude and in the opposite direction as the moon's pull on it. The satellite can sit in a stationary location at that point.

Suppose you have a planet orbiting the sun. A Lagrange point is a place where the forces of gravity from the planet and the sun make for a stable orbit for a third object. Asteroids tend to accumulate at such points because of this stability.

Lagrange Points mark positions where the gravitational pull of two large masses precisely cancels the centripetal acceleration required to rotate with them.

Just a point in space to park a man-made object for long periods of time. Some even speculate that ETs might have advanced probes lurking there to study Earth.

a lagrange point uses existing gravitational forces to "suspend" an object in a stationary point in space.
