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.
I knowe a Poetaster, gainst whom both weake and strong, in company and at home, both heaven and earth, affirme and say, he hath no skill or judgement in Poesie.
—Michel de Montaigne, Essays written in French (trans. By J. Florio_), 1613
