The word "header block" is formed by combining two separate terms: "header" and "block". Here is the etymology of each term:
1. Header: The term "header" originated from the late Middle English word "heder" or "hedur", which meant "person who heads" or "the uppermost course of stones in a wall". It developed from the Old English word "hēafod" meaning "head" or "top". The concept of a header in the context of documents or computer programming evolved later, referring to the introductory section at the top of a page or file containing information such as title, author, date, or other metadata.
2. Block: The term "block" traces its roots back to the Middle English word "blok", which derived from Old French "bloc" and ultimately from Late Latin "bloccus".
