The term 'hypotonic solution' refers to a solution that has a higher solute content dissolved in the solvent than that of the cells cytosol (cell fluids) which is in this fluid, so it is a relative term which depends on the concentration of solvent in the cell(or whatever you are comparing this solution to). The opposite to this is hypertonic.

I think you have it backward. The variable, in a cellular sense, is the solute concentration not the (water) solvent concentration. HyPOtonic means there's less impermeable solute in the water medium surrounding the cell. HypERtonic is when there is a higher impermeable solute concentration in the surrounding fluid.

Woops sry yeah Lobo is right, Hyper = Higher solute content Hypo = Lower solute content

Hope i didnt cause you to lose a mark or 2.
Sorry once again -->stupid mistake
