Confusion about "inheritance": parent-child and OOP

I feel as though I've read the docs fairly carefully, and this difference (especially as a new programmer) doesn't feel explicit enough to me:

**What's the difference between a child inheriting its parent's transform (e.g. if a Sprite is the child of a KinematicBody2D, it moves with the body) and Node2D inheriting from CanvasItem?**

My incomplete understanding is: the latter (Node2D inheriting from CanvasItem) is inheritance in the OOP sense. The former is "inheritance" as in "a few select properties get passed down from parent to child".

All I know is that there's a difference, but I don't know exactly what it is.

A few more points:

1. This confusion could stem from the word "inheritance" being used in two similar-but-different situations.

2. Another way this question could be phrased: **what does it _really_ mean for a node to be a child?** OOP concepts like aggregation are mentioned.

3. My experience in reading the docs is that this relationship is always mentioned, and from working with godot, the difference is absorbed--something just clicks eventually.

If I just completely missed this somewhere in the docs, my apologies.
