As an American, I'm noticing that using "wash" as a transitive verb is tripping me up a little. It sounds ungrammatical to me ear to use it transitively. I'm guessing this could be a difference between American and British English, maybe (if a British speaker says it sounds fine).
I can say, "I wash up every morning" or "I'm wash myself every morning," but "I wash every morning" doesn't say what I'm washing, so it sounds like an incomplete sentence.
Reading the Kwiziq lessons has been great. They're both thorough and concise, which is impressive. Thanks!
