I purchased a faux stone tablet that depicts sheet of music and reads "eniverke". is this a word ?

Google draws a blank. Maybe check your spelling ...
A search of the on-line dictionaries and a look through my huge unabridged dictionary also drew blanks. It doesn't sound like a modern English word, though it could be Old English. It sort of sounds Scandanavian to me, but I'm only guessing.
