A meander is a winding form of a stream or path. But here is another way of using it.
This is a sentence I got from the book I’m reading by J. Maxwell.
Examine a letter, memo, or other items you’ve recently written. Are your sentences short and direct or do they MEANDER?
Meaning…your sentences are going in an aimless, unfocused direction. Like the winding shape of a river or stream.
Other sentence:
His life is meandering. He’s getting nowhere in life.
I guess my presentation has been meandering.
