The word 想到 is formed by combining the character 想 (xiǎng), meaning "to think" or "to miss", with the character 到 (dào), which fundamentally means "to arrive" or "to reach". This creates a conceptual blend where the abstract process of thinking metaphorically "arrives at" or "reaches" a specific point, namely, a thought, idea, or recollection. It captures the moment a thought comes to mind, framing the act of thinking as a journey that culminates in the attainment of a mental object or realization.
