In a way that shows a strong desire or request for something, often with urgency or pleading.
She looked at him beseechingly, hoping he would understand her feelings.
Beseechingly → It is formed from "be-" (meaning to make or cause) and "secan" (from Old English, meaning to seek or request) combined with the suffix "-ingly" (indicating a manner of doing something). The word describes the manner of making a heartfelt request or plea.
Think of someone 'making' a heartfelt 'request' ('secan') — that's why beseechingly means to plead in a heartfelt manner.
