While "linguist" can refer to someone who studies linguistics in general, it also applies to students of linguistics at any level, from undergraduate to graduate.
Here are some other terms you might use:
* Linguistics student: This is a more formal way to describe a student of linguistics.
* Language student: This is a broader term that could also refer to someone learning a specific language, not necessarily studying linguistics itself.
* Linguistics major: This refers to a student who is specializing in linguistics as their primary field of study.
* Linguistics minor: This refers to a student who is taking linguistics courses as part of their studies, but not majoring in the subject.
So, regardless of their specific level of study, a student of linguistics is a linguist in the making!
