The word 增强 is formed through the logical combination of two independent characters, each contributing its core meaning to create a new, unified concept. The first character, 增 (zēng), carries the fundamental idea of "to increase" or "to add". It is placed before the second character, 强 (qiáng), which embodies the quality of "strong" or "strength". Their formation is not arbitrary but follows a conceptual pattern where the action of the first directly modifies the state of the second; thus, to "increase-strength" synthesizes into the single meaning "to strengthen" or "to enhance".
