Blood
The blood radical and blood are the same in looks as well as in meaning.
けつ
ち
None
To remember the reading けつ, we use the word "ketsup." The perfect mix of ketchup and catsup!
The radical is technically blood, but you know that radical is just a drop (of blood) on a plate. So, you ask yourself... Is that really blood on the plate? Could it be? You decide to take a gamble and lick it off. When you taste it, it's definitely not blood. No, it's ketsup (けつ).
