This might seem like a dumb repeated question but I need to confirm 100% so bear with me please.
I started learning Hiragana and I can now write the vowels + the K things. I'm really good at memorizing words and pronouncing and I know lots of Japanese words. I'm saying now, is it advised to try writing the words I already know only with hiragana? For example kako (past) koko (here) etc.. Is that a good idea? Or is it even ok to do at all? And is it correct to write a whole sentence with hiragana?
