So, I'm not studying linguistics and I know the meme(ur major is linguistics? how many languages do you speak? XD) but I'm wondering how common it is to learn languages that have a certain relevancy to the field.
In particular I'm interested whether it is somehow common or at least a little bit noteworthy that some linguists end up learning Lithuanian for example because of its conservative and indo-European grammar.
If this question doesn't make any sense from the perspective of someone who is professionally involved in the field then just let me know.
