'bug-prone' originates from the English word 'bug,' which refers to an error or flaw in a system, and the suffix '-prone,' meaning 'likely to experience or suffer from.'

'bug' was used in the context of errors in the 1940s, and 'prone' has been used since the 14th century to indicate a tendency. The combination 'bug-prone' emerged in the late 20th century with the rise of software development.

Initially, 'bug' referred to insects, but in the context of technology, it evolved to mean 'error.' 'Prone' has consistently meant 'inclined to.'
