How about surprising your husband with a trip to a language immersion program? There are plenty of destinations and programs to choose from depending on his language of interest. For example, if he's interested in Spanish, you could consider a program in Spain or Latin America, or if he's interested in French, a program in France or Canada. You could also consider finding a program that combines language learning with cultural experiences, such as learning to cook traditional dishes or exploring local landmarks.
Another idea could be to set up a home-based immersion program. You could hire a personal language tutor who can come to your home and help your husband with his language learning. You could also purchase language learning software or online language courses to support his learning.
If your husband enjoys reading or watching TV, consider getting him some literature or films in the language he is interested in. This can help him immerse himself in the language and culture while enjoying a pastime he already enjoys.
Or you can get him a star map with the date of your anniversary.
