Question

Is spanning means generate the other element of the vectors?

Answer 1

Spanning means able to generate all the other vectors just by making linear combinations.
For example, the unit vectors i, j, and k span the whole vector space R3 because any vector in R3 can be written as a linear combination of vectors i, j, and k.
