A person who has many skills or can do many different types of work competently, though perhaps not with deep expertise in any single area. Often implies versatility but lack of specialization.
The phrase dates back to the 14th century, originally referring to someone named Jack who could perform various trades. The full original saying was "jack of all trades, master of none," though the negative portion is often omitted in modern usage, reflecting changing attitudes toward generalists.
This phrase has undergone a fascinating evolution in meaning—once clearly pejorative with its "master of none" ending, it's now often used positively to celebrate versatility. In our rapidly changing economy, being a generalist is increasingly valued, making this old phrase surprisingly modern.
The phrase originates in 16th-century England using the generic 'Jack' (common male name) as everyman; 'Jill' was rarely paired until 20th-century feminism. The male default erasure of generalist roles persists.
Use 'generalist,' 'multi-skilled professional,' or 'jack of all trades, master of none' to emphasize the concept rather than the gendered nominal.
["generalist","multi-skilled person","versatile worker","renaissance person"]
Women have historically excelled as polymaths and generalists (Marie Curie, Ada Lovelace, Hedy Lamarr); the gendered 'jack' frame obscures their contributions.
