I was just thinking about putting together some simple grammar practice for myself, but then I realized I don't have any idea what the grammar words are in Japanese. (I don't want to use English and ruin the immersion.)

The idea is to have a verb, then ask for the different conjugations of it, and provide enough time to answer. (Either by blank audio, or pressing a button to continue.)

Anyhow, I don't know the words for things like 'simple present, 'simple past', etc etc. Or even 'noun and verb'!

I could look each one up individually, and hope to get the right word, but I thought I'd ask if anyone here had a nice link instead.

This may be a good place to start. There are some useful terms in the "Word classification" and "Conjugable words" sections.

If you use anki, download the shared deck 'minna no nihongo 1 vocab chapters 1-5'. It has 92 cards (46 unique) at the beginning of the deck that are grammar terms. You could delete the rest of the cards in the deck and have a pretty good starting point.

There's a dictionary of J/E linguistic terms, varying from general to computational linguistics (e.g. systemic functional grammar, lexical functional grammar, adjectives, nouns, anaphora): http://ftp.ftp.monash.edu.au/pub/nihongo/lingdic.txt (Change .txt to .zip for archived extensionless dict file, which you can view in a text editor or Firefox in EUC-JP encoding.)

There's a StarDict version as well, I think it's just called ‘J/E linguistic’ dictionary.

Thanks everyone!
