How about a subscription to an online language immersion program? Some popular options include Duolingo, Babbel, and Rosetta Stone. These programs have interactive lessons and exercises that can help your husband improve his language skills. You could also consider gifting him a language immersion program with a specific focus, such as business language, travel language, or conversation skills. If he prefers offline learning, you could buy him a language course book or a language learning game. Another thoughtful gift could be a voucher or tickets for a language immersion class or retreat that he can attend in person.
Or you can get him a star map with an important date you share.
