wakaru vs. wakatteru vs. wakatta vs. wakaranai vs. wakattena

[goodtastingstea]

lookin for some help on this one! i know one often uses "wakarimasita" as an "Yes, I understand" when things are told to him or uses "wakaru" to ask someone if they understand...but still, it's all a little iffy in my head, especially 'wakatteru' and 'wakattenai'

wakaru
wakatta
wakaranai
wakatteru
wakattenai

can someone please explain the difference...and perhaps provide an example?
thanks in advance!

The 〜て forms of わかる usually imply there's some expectation that the person should already know or does already know what's talked about. It usually takes on a kind of frustrated or annoyed tone. They're often used something like this:

-母：傘を忘れないで。
-Mom: "Don't forget your umbrella."
-生意気な子供：はい、はい。わかってる。
-Cheeky kid: "Yeah, yeah. I know."

-これで三回目。お前は本当にわかってないな。
-"This is the third time. You really don't get it, do you?"

The other 3 don't carry any kind of implication like this. They're simply, "I understand/don't understand."

ah okay, that makes a lot of sense and fits with the situations i've seen them used in before. thanks!!

i've been told わかってる　and わかってるよ can mean like "yeah, yeah, i get, i get" and could come off kind of rude.

It is rather snarky.
