A word with a wide range of meanings
Is there a word that describes a situation where someone says something that has multiple meanings? or can be taken multiple ways.
An example that comes to mind is when someone is being both serious and sarcastic, and they could be taken either way or both ways.
Example:
Person X: Why do you work in the dark?
Person Y: I like the dark side.
Update:
The meanings above are clear and not unclear, or at least if you disagree then please provide a better example.
