My first is in window but not in pane. My second's in road but not in lane. My third is in oval but not in round. My fourth is in hearing but not in sound. My whole is known as a sign of peace. And from noah's ark won quick release.
The answer is "dove." The reasoning behind this is that the riddle describes a word whose first letter can be found in "window" but not in "pane," second letter in "road" but not in "lane," third letter in "oval" but not in "round," and fourth letter in "hearing" but not in "sound." Additionally, the whole word represents a symbol of peace and was released from Noah's Ark.
