Definition: an inferior poet
There are many things of which it is said “you can never have too many,” and listed among these should be “words for an inferior poet.” Our language is infested with such, and if poetaster does not suit your fancy, you may choose from balladmonger, rhymester, versifier, poeticule, bardlet, poetling, or sonneteer.
Such debates aside, Niven's notes are succinct, helpful, and unobtrusive, as well as augmented by a glossary of key names in the back of the book. Only once do they go astray, in his much-remarked gloss of Philip Larkin as a 'hard-right poetaster and trad jazz critic' - yet this is consonant with Bunting's own disdain for the poet ('It isn't so easy to tell Larkin from a corpse’).
