Answer Posted / gk
it is like suppose you have two capacitors connected in series/parallel there will be charge sharing. in mosfet we want the gate capacitance to control channel only.but gate to drain overlapping(coupling) at the end of channel creates capacitance(Cgd) similarly at source also. there is PN junction depletion capacitance at drain/source with substrate completes path. This path creates coupling of input to drain.
