Many
Much, Lots Of
How many evenings are there? There are many.
た
おお
None
To remember the reading た we use the word "taco."
Let's start with the kanji meaning: many. You go outside in the evening (because that's what this kanji is made up of) and are surprised when you're hit by many tacos (た) flying from the sky. For some reason it's raining tacos, and of course you have no idea why.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up what ever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
