There was a lot going on in the last season of Game of Thrones and a number of fans found Stormborn, the second episode of season 7, in particular left them with a number of questions.

The episode showed a tender love scene between loyal Daenerys supporters Grey Worm (Jacob Anderson) and Missandei (Nathalie Emmanuel), whose delicate romance has been building for the past few seasons.

Grey Worm, however, is a eunuch, castrated as a young boy after his merciless induction into the ranks of former slave army The Unsullied.

Because of this fact, several viewers turned to the internet to find out exactly what a eunuch is, with Merriam-Webster, the dictionary publisher and website, reporting that the term had become their most searched word of the night.
