'electrical' originates from the word 'electric,' which comes from the New Latin 'electricus,' meaning 'amber-like,' derived from the Greek word 'ēlektron' meaning 'amber.'

'electricus' transformed into the English word 'electric,' and eventually became the modern English word 'electrical.'

Initially, it referred to the property of amber to attract small objects when rubbed, but over time it evolved into its current meaning related to electricity.
