Five Star Gift Ideas

How about a language learning book, like "Fluent Forever: How to Learn Any Language Fast and Never Forget It" by Gabriel Wyner or a subscription to an online language learning platform such as Duolingo Plus or Babbel? You could also plan a trip to a destination where the language she is learning is spoken so she can practice speaking it in a real-life setting. Another idea could be coordinating a language exchange with a native speaker for her to practice speaking with. Lastly, consider creating a personalized gift basket with items related to the language she's learning -- think language guides, maps, food, music, and literature from a country that speaks the language she is learning.

Or you can get her a star map with the date of your first kiss.
