# Superstring Coordinates

In Cumrun Vafa's "Lightning Introduction" to string theory in his Lectures on Strings and Dualities , he instroduces supersymmetry to string theory thus:

in addition to the coordinates $$X^{\mu}$$ we also have anti-commuting fermionic coordinates $$\psi_{L,R}^{\mu}$$ which are spacetime vectors but fermionic spinors on the worldsheet whose chirality is denoted by subscript L, R.

I have no problem with the anti-commutative coordinates themselve, but how does the worldsheet make vectors in spacetime appear as spinors?
