Vellicate is a verb that means to twitch.
The Latin word vellicare (vel ee CAR ay) means ‘to pluck or pull.’ By the early 17th century the word was brought into English and had taken on the more specific meaning it has today. It now refers to an involuntary twitch. Here’s an example:
When my eye began to vellicate, I panicked immediately. The last time a twitch like that came to my eye, I would up having a very serious eye condition.
