How about gifting him a subscription to an online language learning website or app? This would allow him to learn at his own pace and convenience. You could also consider purchasing him a book or audio course set for the language he is interested in. Another idea would be to find a language tutor for him to work with either online or in-person if that would interest him. This would allow him to have a more personalized and interactive learning experience. Or, you could plan a trip to a country where the language is spoken and make it a language immersion experience for him!
Or you can get him a star map with the date when he was born.
