Meaning of “wakarimi (わかりみ)”

It means “I can understand (and I agree)”.
It’s a teenage slang and young girls often use this.

“wakari(わかり)” is from “wakaru(わかる)” which means “understand”.
“mi(み)” is hard to explain but I think it’s same “mi” with “arigatami (ありがたみ)” which is a noun not a slang and it means “thank”.
This “mi” may changes “wakaru(this is a verb)” to noun in my opinion.
If you can understand “mi”, you can also understand other “(something) + mi” teenage slang.

Tsurami(つらみ)
It means “I’m depressed just a bit”.
“Tsura(つら)” is from “tsurai(つらい)” witch means “be depressed”.
“+mi” is a way of teenage slang, so it sounds like something funny not serious so I added “just a bit”.

Yosami(よさみ)
It means “It’s good”.
“Yosa(よさ)” is from “yoi(よい)” witch means “good”.

By the way, let’s go back to the main subject.
Wakarimi means “I can understand (and I agree)”.
You can use also like these. Both of them mean “I can really understand (and I agree)”.
