Marginal jotting is a term used to describe the act of making brief notes or observations in the margins of a document. It is often used to make quick reminders or to record ideas that come up during the reading process. The term 'MARGINAL jotting' is made up of two words: 'MARGINAL' and 'NOTATION'. 'MARGINAL' is a four-letter word meaning 'on the edge or border' while 'NOTATION' is an eight-letter word meaning 'a system of symbols used to represent numbers, quantities, or other information'. Together, these two words form the term 'MARGINAL jotting', which describes the act of making brief notes or observations in the margins of a document.
