IPA: /ˌætrəˈbɪliəs/
KK: /ˌætrəˈbɪliəs/
Describing someone who is often in a bad mood or feels sad and gloomy.
His atrabilious nature made it difficult for him to enjoy social gatherings.
Atrabilious is derived from the Latin "atra" (meaning black) and "bilis" (meaning bile). The term originally referred to a person who was melancholic or irritable, as it was believed that an excess of black bile caused such temperaments.
Think of 'black' ('atra') and 'bile' ('bilis') to remember that 'atrabilious' describes someone with a gloomy or irritable disposition.
