Lessons in the book include words to use when getting ready to leave the house, phrases you can use at the beach, and Manx sayings for holidays such as Christmas.
Mr Cain said it was “unlikely” parents’ grasp of the language would “ever be as good as the children’s, because of amount of exposure pupils get at school”.
“But, using the book, hopefully the kids can hear a bit more Manx outside of the school environment and share the learning process,” he said.
A former Manx language officer he said the booklet, which is filled with everyday phrases, would also help those interested in learning some “colloquial Manx”.
“There’s plenty of Manx in there which is accessible and useful for anyone who is keen to learn,” he added.
