cantankerous
UK[kænˈtæŋkərəs]US[kænˈtæŋkərəs]
adj
bad-tempered, argumentative, and uncooperative
Etymology
the origin of 'cantankerous' is somewhat obscure, though it likely emerged in the 18th century. it is thought to be an alteration of an earlier english dialect word, perhaps influenced by middle english 'contakour' meaning 'troublemaker', or possibly related to the irish word 'cannrán' meaning 'grumbling'. the '-ankerous' portion may have been shaped by association with words like 'rancorous'. the word's journey reflects a folk etymology process where sounds were blended to create a uniquely expressive term for a quarrelsome disposition, with no direct, clear lineage to classical roots.
Analysis
the word is considered a simplex form. its exact morphological breakdown into meaningful substrings from its current spelling is not clear or standardly recognized.
