Words Have Meaning(s)

When we (I) think of consume, we (I) think: ingest, take in, absorb. That's the definition, basically. Consume comes from the Latin word "consumo," which means to take altogether, to spend, to use up, to finish. The derived noun, "consumptio," means a consuming, destroying. A "consumptor" is a destroyer. "Consummo" means to form a whole, complete. The Latin prefix "con" means with. "Sum" is the present singular of "to be." Con+sum = "to be whole." When we (I) want someone, we want to consume them (metaphorically of course, right?). So, do we (I) want to destroy them, or be whole with them? Is there a difference?
