Narrative:
Aircraft X; a student solo; called up ready for departure. I had aircraft Y on a 2.5 mile final. I asked aircraft X if they could accept a no delay departure. Aircraft X responded; 'say again?' I instructed aircraft X to hold short. I received a clear read back of hold short instructions. Then I instructed another aircraft on the downwind to extend downwind; with traffic holding in position phraseology. His reply was garbled; but I understood it on position. As the downwind aircraft had a bad radio all flight; I paid no extra attention to the garbled read back. Aircraft Y then asked; 'is there an aircraft on the runway?' at that time I saw aircraft X on the runway and sent aircraft Y around.
