What does thought mean?
Thought is a central English word for the ideas and mental processes that shape how people understand the world. As a noun, it can name a particular idea, belief, or opinion, as in “She had a thought,” or refer more broadly to the activity of thinking, as in “He was lost in thought.” In some contexts, it also means an intention or purpose, especially in phrases such as “I had no thought of going there.” As a verb, thought is the simple past and past participle of think, expressing that a belief, opinion, or plan existed at an earlier time. The word appears in both everyday conversation and more reflective or literary writing, ranging from casual suggestions to discussions of philosophy and consciousness. Its unusually broad range makes it useful for describing not only what someone has in mind, but also the act of considering a question and the earlier state of knowing or believing something.
An idea, belief, or opinion formed in the mind; the mental process of thinking or considering something.
"The thought of moving abroad had been with her for years."
The noun may denote either a single idea or, more generally, the activity of thinking and reflection.
The simple past and past participle of think.

This form is used to state a belief, opinion, intention, or plan held in the past.
The plural is commonly used for ideas, opinions, or reflections, especially when they are being shared or exchanged.

Long before it named an idea, “thought” referred to the action of thinking: a linguistic fossil of the verb “think.”

Where does thought come from?
The English noun descends from Old English þōht, a verbal noun formed from þencan, meaning “to think.” In Middle English it appeared as thoght and eventually developed into the modern form thought. The English verb form is likewise the historical past form of think. Dutch gedachte, German Gedanke, Danish tanke, and Swedish tanke are related Germanic cognates reflecting the same broad inheritance.
