Translate "A Long-expected Meeting" into Sindarin

Best I can come up with is:

i cova and

I would say Hûd vronadui "[A] Enduring gathering".

The meeting is long-expected, not long-enduring. I.e., it has taken a long time for the meeting to ever take place.

Yes, that is N. bronadui adj. “enduring, lasting”, but I suppose you could do "[A] gathering that does not end" Hûd i ú-dêl.

Or Hûd údelol "[A] not-ending gathering"

Long-expected, as in expected but not happening for thousands of years...

I.e., "Will this meeting ever happen?", not "Will this meeting ever end?"

Oops miss read that! Maybe something with ᴺS. !hora- v. “to await, expect”.

Hum....e·Chûd chorannen "the awaited gathering"

Thanks!
