The pronunciation of percolate as (pûr′kyə lāt′),USA pronunciation 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)USA pronunciation is followed by some other vowel, the (y)USA pronunciation represents a hypercorrection. The pronunciation of escalate as (es′kyə lāt′)USA pronunciation is another such example. See coupon, new.
