His priggery made it difficult for him to connect with others who had a more relaxed attitude towards life.
Priggery originates from the word 'prig' (from Middle English 'priggen', meaning to steal or to be prim) combined with the suffix '-ery' (meaning a state or condition). The term refers to the state of being priggish, characterized by excessive propriety or self-importance.
