The word "峥嵘" is formed by combining two characters, both constructed with the mountain radical (山) to semantically associate them with mountainous terrain, and each incorporates a phonetic component (爭 in 峥 and 荣 in 嵘) to approximate their pronunciations; this juxtaposition creates a compound where the repeated semantic element emphasizes meanings related to towering height or steepness, resulting in a cohesive term denoting loftiness and prominence.
