Morphology
theta + rhythm
While 'rhythm' (regular pattern) is transparent, 'theta' is a specialized label (Greek letter / technical term) and does not by itself signal 'brainwave pattern' to an average B1 learner. The phrase is only partly compositional — it denotes a type of rhythm but requires domain knowledge (EEG terminology) to arrive at the specific meaning — so it is not fully transparent.
Etymology
Theta rhythm was named when early brain recordings showed slow, repeating waves that reminded scientists of the Greek letter theta, and rhythm describes their steady beat. So, theta rhythm now means the brain's low, slow activity when a person is 'relaxed' or ready to fall asleep.
