Morphology

phrenitis = phren (semi-transparent) = phren + itis

The suffix '-itis' clearly signals 'inflammation' (transparent), but the root 'phren' is an obscure combining form not familiar to average learners, so the overall meaning is not fully guessable.

Etymology

Phrenitis comes from the root phren meaning 'mind' and the ending -itis meaning 'inflammation', the same ending you see in words like tonsillitis or arthritis. So phrenitis literally meant 'inflammation of the mind' and was an old medical name for a brain infection that caused fever and confusion.
