* σημεῖα (sēmeia): This is probably the closest general translation. It refers to signs, marks, signals, or wonders. It's often used in a broader sense, encompassing both natural omens and deliberately created signals.
* συμβόλαια (symbolaia): This word means "symbols" or "tokens," often implying a deeper, more symbolic meaning than just a simple sign.
* τεκμήρια (tekmēria): This refers to "signs" or "evidences," often in the context of proof or inference.
* σημαίνειν (sēmainein): This is a verb meaning "to signify," "to mean," or "to be a sign of." While not a noun, it's relevant if you're looking for a word related to the action of signifying.
To choose the most accurate word, you'd need to specify what kind of "signs" you're referring to.
