Monstruomental 

(adj.): Relating to a mind that possesses exceptional ability or talent that is abnormal or extraordinary. "Monstruo" is derived from the Latin root word "monstruosus" meaning 'extraordinary', and "mental" is derived from "mentalis" meaning 'of the mind'.

Shakespeare's monstruomental ability allowed him to neologize or 'coin' new words.
