[pur-kyuh-leyt] , with an intrusive y-glide, results from analogy with words like circulate and matriculate, where the unstressed vowel following the k-sound is symbolized by a u spelling, making the y-glide mandatory. In similar words where [k] is followed by some other vowel, the [y] represents a hypercorrection. The pronunciation of escalate as [es-kyuh-leyt] is another such example.
