Morphology
delta + rhythm
The phrase combines a technical label 'delta' with the general noun 'rhythm', so a learner who knows both words can infer this refers to a kind of rhythm or wave, but they will not be able to derive the specific neuroscientific properties (1–4 Hz, high amplitude, deep sleep) without domain knowledge. Because 'delta' functions here as a specialized scientific term rather than a transparent semantic modifier, the relation is partially clear but not fully predictable to a B1 learner.
Etymology
The term delta rhythm names very slow, large brain waves that appear during 'deep sleep'. Think of them as slow, heavy waves or a slow drum beat in the brain: delta points to their slowness and size and rhythm to the steady repeating beat, so seeing delta rhythm on a brain scan means the person is in 'deep sleep'.
