Origin

The character 糧 combines rice (米), the basic component for grain and food, on the left side with 量 on the right, which serves as a sound hint suggesting the pronunciation. The left-side rice radical immediately signals that this character deals with grain or food provisions. The right component doesn't add meaning but rather tells you roughly how to say the character — similar to how many Japanese characters pair a meaningful radical with a sound guide. Together, this visual pairing efficiently combines "what it is" (rice and food) with "how to say it" (the sound hint), creating the word for provisions or foodstuffs.
