technobabble

Technobabble was formed by combining techno- (meaning "technical or technological") with babble ("continuous meaningless vocal sounds"), and unsurprisingly suggests language which sounds highly technical and is incomprehensible to the listener. Techno- as a combining form has given English speakers a number of interesting words, including but not limited to technocrat, technophile and technophobia, techno-thriller, technopreneur, and even technostructure ("the network of professionally skilled scientists, engineers, and administrators that tends to control the economy"). Techno- itself traces back to the same root word that gave us technology, namely the Greek word technē, meaning "art, craft, or practical skill."
