Third person singular present tense of 'think'; to have thoughts, form opinions, or use one's mind to consider something.
From Old English 'thencan' meaning to conceive in the mind, related to 'thank' (originally meaning to think). The Germanic root meant 'to cause to appear to oneself,' revealing thinking as an act of mental visualization.
The connection between 'think' and 'thank' isn't coincidental - gratitude was originally seen as a form of thinking, specifically thinking well of someone. This ancient link suggests our ancestors understood that appreciation is fundamentally a cognitive act, not just an emotion.
