The word 至极 is formed by combining two characters, each carrying a core idea of an extreme endpoint. The first character, 至, pictorially represents an arrow hitting a target, conveying the concept of "arriving at" or "reaching" a point. The second, 极, originally depicted the highest roof beam of a house, symbolizing the "utmost limit" or "pinnacle". When placed together, they create a powerful, stacked meaning: one reaches (至) the absolute extreme limit (极), forming a single concept of ultimate extremity or perfection.
