Great to hear that you're having a go at the Manx and that you are enjoying it. There are some big differences between Manx and English although they might not always be obvious at first. Differences such as starting with a verb: Ta Bob goll - Bob is going; mutations etc etc. Some structures can be more Gaelic or more English in their structure: I can play tennis could be: Foddym cloie tennis or the more Gaelic Foddym tennis y chloie.
Don't worry about that though, just enjoy saying ta mee geearree loayrt Gaelg rhyt!
