IPA: //ˈpoʊɪˌtæstər//
KK: /ˈpoʊɪˌtæstər/
A person who writes poetry that is considered to be of low quality or not serious.
Despite his efforts, many critics labeled him a poetaster for his simplistic verses.
Poetaster is formed from "poet" (from Latin "poeta", meaning a maker or creator) and "-aster" (a diminutive suffix in Latin, meaning little or lesser). The term poetaster refers to a person who writes poetry, often implying a lack of skill or quality, thus suggesting a lesser poet.
Think of a 'poet' as someone who creates poetry, and the '-aster' means 'little' or 'lesser'. This helps you remember that a poetaster is someone who writes poetry but is considered to be of lesser skill.
