Notes on Usage

• "Cao tốc" as a Standalone Word: In modern Vietnamese, "cao tốc" is primarily used as an adjective. Its standalone use as a noun (e.g., to mean "highway") is less common and typically understood only within the context of a previously mentioned noun like "đường". For clarity, the full compound noun (e.g., "đường cao tốc") is preferred.
• Context is Key: The meaning is almost always related to transportation (trains, boats, roads) or data/communication technology (internet). In technical fields like aviation or mechanics, it specifically denotes high rotational or vibrational speeds.
