How it is used
- Approachability - the quality of being easy and warm to be around: 这位主持人很有亲和力 (zhè wèi zhǔchírén hěn yǒu qīnhélì) this host is very approachable.
- Almost always in 有/没有亲和力 (yǒu/méiyǒu qīnhélì, to have/lack warmth). Prized in hosts, teachers, and salespeople.
- Also the chemistry term 'affinity', but the people sense dominates everyday use.
