I want to know the answer to the following question:
What combines "grain radical" with the "mouth radical"?
All the background I'm provided with is that "For instance, he 和 "harmony, peace", which combines the "grain radical" with the "mouth radical", has infrequent variants 咊 with the radicals reversed and 龢 with the "flute radical".". Is that enough to answer the question?
Answer: yes
