31 d the original source of motive power [5&5 letters] punched in the letters on my spellchecker and obviously the answer is PRIME MOVER. but the other one that came up was PRIZE MONEY, makes you think doesnt it ?
Hi Dee ..I put Prime Mover going on the fact that prime means first ......One regarded as the initial source of energy directed toward a goal or initial force that generates or moves something .....however the Prize Money could certainly motivate me to spend it !!!
