Be mindful of the context to distinguish between the literal (swallowing) and figurative (understanding) meanings.
The verb is versatile but context determines whether it refers to swallowing or understanding.
From 飲む (nomu, to drink) + 込む (komu, to enter or go into). The verb combines the action of drinking with the idea of something entering the body.
While primarily used for swallowing, it can also be used metaphorically to describe understanding something quickly. The literal and figurative meanings are distinct but both are common.
