Expert

/ˈɛkspɜːrt/ noun, adjective

Definition

Noun: A person who has deep knowledge or skill in a particular area. Adjective: Having or showing special skill or knowledge.

Etymology

From Latin *expertus* ‘experienced, tried’, past participle of *experiri* ‘to try, test’. An expert was originally someone ‘proven by trial’.

Kelly Says

An expert isn’t just someone who knows a lot; they’re someone whose knowledge has been tested again and again. The word quietly reminds us that real expertise is earned through experiments, failures, and corrections over time.

Ethical Language Guidance

Gender History

The label “expert” has often been more readily granted to men, especially in technical and scientific fields, while women and non‑binary people with equal or greater qualifications are framed as exceptions or assistants. Media and institutional practices have historically under‑invited women as expert commentators and principal investigators.

Inclusive Usage

Apply “expert” based on demonstrated knowledge and credentials, not gendered expectations about who “looks” like an expert. When giving examples, include women and underrepresented genders as experts across domains.

Inclusive Alternatives

["specialist","authority","professional"]

Empowerment Note

Women such as Ada Lovelace, Katherine Johnson, and countless others have been core experts in mathematics, computing, and science yet were long omitted from expert narratives; naming them helps correct this bias.
