1. "Wast": In Old English, "wast" is the second-person singular form of the verb "to be" in the past tense. It is derived from the Proto-Germanic word "wēs" and is related to the modern English verb "was".
2. "Dumbstruck": This word is a compound of two elements. "Dumb" comes from the Old English word "dumb" meaning "silent" or "mute", which is related to the Old High German word "tumb". "Struck" is the past participle of the verb "strike", meaning to hit or impact forcefully. The word "dumbstruck" was first recorded in the 17th century, meaning to be struck silent in astonishment or awe.
