The word 推进 is formed by combining two independent characters, each with its own core meaning, to create a new, unified concept. The first character, 推 (tuī), carries the fundamental idea of "to push" or "to shove", implying an application of force. It is joined with 进 (jìn), which means "to advance", "to enter", or "forward movement". Their combination is not merely additive but conceptual; the action of "pushing" is directly applied to the state of "advancing", resulting in the composite meaning of "to propel forward", "to drive", or "to promote", conveying a sense of active and forceful progression.
