You know you're a language nerd when…

[badger]

you get more target-language & language-learning books for xmas than native-language ones.

[garyb]

You have a dream about being sent promotional material for Anki.

[Iversen]

You could risk being called a nerd when you write something like a whole small book about music history in so many languages that the vast majority of those that potentially might be interested in the subject can't read it.

[Mooby]

...when one part of your mind is fully engaged in learning your target language while another part of your mind is simultaneously exploring other language possibilities.

You believe you've found the deal of the century: Assimil for £1!



But you already own the same course in another base language so you resist and hope that some deserving learner takes advantage.

[Serpent]

...you realize that Russian spam means language practice!

When you know you can trust another mod to deal with Russian spam

In addition to Croatian, the cat is also learning Turkish and Polish via Glossika.

When your cat is learning three languages.

[IronMike]

...when your wife commends you for your restraint when you are bowling next to a Russian-speaking family and you don't say a word to them.

... You have a favourite word in Greek, dating back from before you were even learning the language.
... You insist in writing all the accents and breathings in Modern Greek, to the confused amusement of your poor professor.
... You are strongly considering learning Persian since then you might be able to persuade your Iranian-American friend to learn their own language.
... You are taking a course in historical Italian philology.
... You ask the professor of that course if you can write your final paper in Latin.
... You do not like referring to any one language as your "native" tongue, since it has gotten so corrupted by interference from other languages.
... You are having a discussion as to which modern variety of Chagatai would be most worth learning to access the largest amount of texts the most easily. (The answer probably would have been Uygur, but it is probably just best to start right with the classical language unless you are specifically interested in Uygur or Uzbek, since resources for the modern versions are rather challenging to find.)

One of my favorite games is called "Confuse my internet browser" by changing the language settings every day. Google Chrome can't decide if my search results should be in Finnish, Swedish, Hungarian, or Spanish !
