signs
The noun usage carries a duality between the physical and the abstract. A physical sign is a tangible marker, like a neon billboard or a stop sign, designed to direct or alert. In contrast, an abstract sign is a symptom or a clue, often requiring interpretation to understand a hidden truth or a future event.
Countable when referring to individual markers or gestures like a stop sign. Uncountable when referring to the general act of signaling or the overall presence of indications.
