On: Reasons some languages are harder to learn

[deeteecee]

I'd stick to the common ones, you don't need to learn them all.

[glandium → deeteecee]

Whether you want it or not, you'll end up encountering them, not necessarily with enough context to tell you what they are. Example from regular news: 1000軒停電.1000世帯停電.1000戸停電.(and they all point to something slightly different)

Of course, it depends what you use Japanese for.

[deeteecee → glandium]

Yes, it does depend. My recommendation would still be to follow up with what I said and master the common ones used for basic conversation first. Then work on the rarer ones that pop up in the news or when you're renting apartments or whatever.
