I have a conjecture, that we understand language primarily through proprioception. So when we see and hear someone talking, we mirror and model their muscle movements, and we understand it fundamentally, in terms of our own body moving. I suspect proprioception plays a role in abstract thinking, too. Conceptual metaphors are movement based, as if our hands were manipulating thoughts. We pick ideas apart, reassemble them, sort through them, toss them out.
