Etymology
The word 'carrier' is a transparent English formation, combining the verb 'carry' with the agent suffix '-er'. The verb 'carry' itself has a journey from Latin carrus, meaning a wagon or cart, through Old North French carier. This root is shared with words like 'car' and 'carriage', all connected to the concept of wheeled transport. The suffix '-er' is one of the most productive in English for forming agent nouns. Thus, the literal meaning "one who carries" logically extends to its modern applications, from a person bearing goods to a company transporting them, and metaphorically to a vehicle, ship, or biological entity that 'carries' something from one point to another.
