Here are some examples of how it can be used:
* διάφανη ύλη (diafani yili) - transparent material
* διάφανη μεμβράνη (diafani membraní) - transparent membrane
* διάφανος ουρανός (diafanos ouranos) - clear sky
It's important to note that while "διάφανος" encompasses both "clear" and "transparent," there are other Greek words that can be used depending on the specific context. For example, "καθαρός" (katharos) can also mean "clear" when referring to water or air, while "σαφής" (safis) can mean "clear" when referring to something that is easy to understand.
