What does understood mean?
Understood is the past tense and past participle of understand, with additional adjectival uses in fixed expressions. It describes having grasped the meaning, significance, or implications of something, as in “I understood the reason for her decision.” It can also convey that a conclusion, intention, or fact has been inferred from context, even when it was not stated directly. In the expression “it is understood,” the word suggests a point regarded as evident or agreed upon by the people involved. The word is equally natural in everyday conversation, academic writing, and formal announcements. Because it can refer both to completed acts of comprehension and to shared assumptions, understood is useful when discussing what people know, recognize, or take for granted.

Where does understood come from?
Understood derives from Old English understandan, a compound formed from the elements under and standan, meaning “to stand under” or “to stand among.” The compound originally conveyed being positioned among or beneath something and later developed the sense of taking in the meaning of an event or statement. Its modern forms belong to the same English word family as understand and understanding, while stand and under preserve the two elements of the historical compound.
