Ardently- adjective

Ardently means characterized by warmth of feeling typically expressed in eager support or activity

Meriam- Webster’s dictionary

“Quicksand” by Nella Larsen

“Suddenly she hated then all. Strange, too, for this was the thing which she had ardently desired to share in, to be a part of this movement to one man’s genius and vision”

I understand the meaning of this word in this context because it is saying that she was eager to share what she had to share.
