A great anniversary gift for your language-loving husband could be a subscription or a set of language-learning software or books. This way, he can continue to explore new languages and stay engaged with his passion. Another idea could be a weekend getaway to a place where the language he is learning is predominantly spoken, so he can practice speaking with locals and really immerse himself in the culture. You might also consider some international cuisine cooking classes that correspond with the languages he's interested in learning, so he can experience the food of the region while practicing the language.
Or you can get him a star map with the date of your anniversary.
