The word 察觉 is formed by combining two characters, each contributing a layer of meaning that flows into a single concept. The first character, 察 (chá), carries the core idea of close examination, scrutiny, or investigation, like looking into details. The second, 觉 (jué), conveys the sense of feeling, sensing, or becoming aware. When joined, they create a semantic sequence where the deliberate act of examining (察) naturally leads to the resultant moment of awareness or realization (觉), picturing the process of noticing something through attentive observation, much like a detective who examines clues until he becomes aware of the truth.
