How about getting your friend a subscription to an online language immersion program? There are many great options out there that offer interactive lessons, conversation practice with native speakers, and cultural immersion activities. Some popular programs include Rosetta Stone, Babbel, and Duolingo Plus. You could also consider purchasing a book or set of books in the language your friend is interested in, along with a dictionary and a notebook for them to practice writing and vocabulary. Or, if your friend loves to travel, consider gifting them a trip to a country where they can fully immerse themselves in the language and culture.
Or you can get her/him a star map with an important date you share.
