Morphology

electroencephalograph = encephalograph (semi-transparent) = electro + encephalo + graph

The word is built in a largely literal way from classical combining forms, but it remains a technical medical term that is not fully transparent to average learners.

Etymology

The word electroencephalograph comes from three parts: electro- meaning 'electricity', encephalo- meaning 'brain', and -graph meaning 'to write or record', like in autograph. So an electroencephalograph is a machine that 'writes down' the brain's electrical signals, which is why doctors use it to record brain activity.
