Initial by意思
"Initial by" is a term that is often used in the context of signing documents or agreements. It means to sign with your initials, which are the first letters of your first and last name. For example, if your full name is John Doe, your initials would be J.D.
In some cases, "initial by" may also refer to the act of signing one's initials as a form of acknowledgement or to indicate that one has read and understood a particular section or term of a document. This is often done in addition to or instead of a full signature.
