Pervicacious

Pervicacious is an adjective that means obstinate or extremely willful. The Latin word vincere (VEEN chair ay) means ‘win.’ Our word of the day combines this word with the prefix P-E-R, meaning ‘thoroughly.’ You could say that a pervicacious person is someone who is thoroughly committed to winning all the time. For example: Grandpa’s pervicacious rejection of new technology made it difficult to teach him a new language. It wasn’t easy to find a Spanish lesson that I could play on a gramophone.
