This noun denotes what passes through the mind—a thought, notion, or purpose. In Acts 8:22, Peter confronts Simon Magus about the intention of his heart, the underlying thought driving his desire to purchase the Spirit's power. Classical Greek used this word for inventive thinking and creative conception, but also for darker purposes and designs. The multilingual evidence shows semantic range: Spanish pensamiento suggests general thought, while English 'intent' and the domain assignment point toward purposeful mental activity.
