Meaning
Two hands pressed together, palms touching and fingers pointing up. Depending on culture and context it means thank you, please, prayer, hope, or a respectful bow, and many people use it for all of these.
As thanks: โThanks so much for covering for me today ๐โ As a request: โPlease send the file before noon ๐โ Some readers also see a high five, which is a common misreading rather than its usual meaning. Since โpleaseโ and โthanksโ are close but not identical, a few words make it obvious which one you intend, and in religious conversations it is best used sincerely.
