1. "Wast": This is an archaic form of the verb "was" in the second person singular past tense. In Middle English, it was commonly used to refer to "you were" or "thou wast", but its usage has fallen out of favor in modern English.
2. "Successful": This term has a Latin origin. It is derived from the Latin word "succedere", which means "to succeed" or "to come after".
