(xìng) — (suffix) forms abstract nouns from adjectives or verbs, indicating a quality, property, or state

Definition

A suffix meaning '-ness / -ity' that turns an adjective or verb into an abstract noun for a quality (e.g. 安全性 = 'safety'). On its own 性 means 'nature' or 'sex'; here it's the combining form, not the standalone noun.
