Hard to follow The King's Speech (6)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

H (hard) after ELVIS (the King). It’s far from clear to me how ‘speech’ defines the solution. OK, I’ve just searched. AI tells me: ‘In JRR Tolkien’s mythology, “Elvish” can mean “speech” because the Elves’ very name for themselves – Quendi – literally translates to “the speakers”. This linguistic connection reflects their history as the first beings in Middle-earth to develop articulate language.’ Well, you do indeed learn something new every day.
