The kanji 極 is a phono-semantic compound (形声文字). The left side is 木 (ki, meaning "tree") and the right side is 亟 (kyoku, meaning "urgent" or "suddenly"). The original meaning may have related to the top of a tree. The idea evolved to mean the highest point or the utmost limit. The 亟 part provides the sound and contributes to the overall meaning of "reaching the limit" or "extremity". The 木 component provides the semantic element. Over time, it came to represent "extreme" or "utmost".
