'Alexa' originates from the name 'Alexandra,' which is derived from the Greek name 'Alexandros,' where 'alexein' meant 'to defend' and 'aner' meant 'man.'

'Alexandros' transformed into the Latin name 'Alexandra,' and eventually became the modern name 'Alexa.'

Initially, it meant 'defender of man,' but in modern usage, it refers to a virtual assistant developed by Amazon.
