IPA: /ˈhɛdər/
KK: /ˈhɛdər/
A part of a document or webpage that appears at the top and usually contains the title or other important information.
The header of the report included the title and the author's name.
Header → The word 'header' is formed from 'head' (from Old English 'heafod', meaning the upper part or top) and the suffix '-er' (meaning a person or thing that performs a specified action). A header is something that is at the top or serves as a title or introduction.
Think of 'head' as the top part of something, and the '-er' indicates it is something that serves a purpose at the top — that's why a header is at the top of a document or section.
