chairperson
Word family
Synonym discussion
Sense: noun/1
All four words refer to someone who leads a meeting or group, but they differ in formality and gender specificity. Chair is the shortest and most neutral option; it is widely used in everyday workplace English and carries no gender implications. Chairman is the oldest term but implies a male holder; some organisations use it regardless of gender, though this is becoming less common. Moderator is narrower: it describes someone who keeps a debate, panel discussion, or online forum on track rather than managing a standing committee's ongoing business. Presiding officer is the most formal and is typically restricted to parliamentary procedure, courts, or high-level legislative meetings. For general use in modern English, chair or chairperson are the safest choices.
Etymology
Chairperson was formed in the 1970s as a gender-neutral alternative to chairman. The word combines chair (referring to the position of authority at a meeting, from Latin cathedra meaning 'seat') with person (from Latin persona meaning 'individual'), replacing man to avoid implying that only men could hold the role. It gained widespread use in official and organisational language from the 1980s onward.
