Was William of occam a realist or a nominalist?

William of Ockham is primarily associated with nominalism. He argued against the existence of universal entities beyond individual things, asserting that universals are merely names (nomina) we use to describe groups of individual objects. Ockham emphasized simplicity and economy in his philosophical approach, famously advocating for the principle known as Ockham's Razor, which suggests that one should not multiply entities beyond necessity.
