The word 危害 is formed through the semantic combination of its two component characters: 危 (wēi), which conveys the core idea of "danger", "peril", or "being endangered", and 害 (hài), which means "harm", "damage", or "injure". They are combined not grammatically but conceptually, where the first character defines the state (danger) and the second character specifies the resultant action or effect (causing harm). Together, they create a single, fused concept meaning "to jeopardize" or "to cause damage and danger", where the danger inherent in 危 actively brings about the harm denoted by 害.
