Free grammar resources.

I'd like to plug two grammar resources I used early in my journey which I felt helped me immensely.

Tae Kim's Guide to Japanese Grammar: https://guidetojapanese.org/learn/category/grammar-guide/grammar-start/

The book covers many different vocabulary points. I highly recommend using it as you run across new grammar for detailed explanations. It can help decipher some of the harder grammar points.

Cure Dolly is, well, weird. The robot avatar causes some uncanny valley effect, but her ability to visualize grammar points can really help when you're in a pinch. I use her videos as a secondary resource when I'm really struggling to grasp a grammar point.

A couple very dedicated Japanese learners created an entire transcript of her videos, so you can enjoy Cure Dolly content without the robot avatar:

Please note, Cure Dolly is no longer active. Sadly, there are assumptions she passed away.

Some grammar points take multiple resources to really grasp, but it is also good to keep in mind that exposure will help the most. Expose yourself to as much Japanese as possible through immersion, and the small nuances between grammar points will become clear.
