This video utters the concept of neighbourhoods of a point. I hope it will be productive for you.
Neighbourhood (topology)
In a topological space, a set is a neighbourhood of a point if (and only if) it contains the point in its interior, i.e., if it contains an open set that contains the point. However, neighbourhood systems can also be characterized axiomatically and then be used to define the corresponding open sets.
