A "gram" is a word ending in the suffix -gram, and is usually a type of message or image.

Etymology of -gram

The English suffix -gram means "something written, drawn, or otherwise recorded", and is derived from the Ancient Greek suffix -γραμμα (-gramma) based on the word γράμμα (gramma), meaning "written character, letter, that which is drawn"), which is in turn derived from γράφω (graphō), meaning "to scratch, to scrape, to graze".
