thinks

Thinks is the third-person singular present tense form of the verb think in English. The base verb think denotes the mental act of using the mind to consider, reflect, form beliefs, opinions, or judgments, and to suppose or imagine. When the subject is he, she, or it, the present tense adds -s, yielding thinks.

Grammatical notes: Think is a verb with related forms think, thought, thinking, but its present tense follows the regular pattern for third-person subjects. Do-support is used for questions and negations: Does he think so? He does not think so.

Usage: Thinks expresses belief, opinion, or inference about present or future events. It can express uncertainty (I think it might rain), judgment about plans (I think this is correct), or speculation (What do you think?). In some contexts it can appear in formal or old-fashioned constructions, such as "It is thought that..." for the passive reporting of beliefs.

Etymology: Think derives from Old English thencan or þencan, related to other Germanic cognates, with sense development from “to hold in the mind” to “to form beliefs” and “to consider.”

In philosophy and cognitive science, think is used in discussions of reasoning, deliberation, and intentional states, and appears in phrases like critical thinking or conscious thinking.
