I observe the following definitions in Dictionary.com:
adjective
- having or seeming to have no end, limit, or conclusion; boundless; infinite; interminable; incessant: an endless series of complaints; Time is endless.
- made continuous, as by joining the two ends of a single length: an endless chain or belt.
And
adjective
- having or likely to have no end: never-ending worry.
Both definitions seem quite equivalent to me. Is there any circumstance when one should be used instead of the other?
To give a practical example: are these equivalent?
