settlement, obtain, reap, pay, supply, store
納 centers on bringing something in and securing it: receiving payment, storing supplies, reaping a harvest, or reaching a settlement where things are put in their proper place.
納 combines 糸 (thread) with 内 (inside), suggesting the idea of threading something inward or putting it inside. This likely developed into the sense of receiving, storing, or paying.
Thread 糸 is pulled inside 内, like drawing a payment into a storehouse or reaping a harvest into storage. The thread brings things in and secures them.
For ノウ, imagine a farmer saying 'Now!' as they reap the harvest and store it inside: Now -> ノウ, and the thread pulls everything in.
