Morphology
The phrase is compositionally transparent in that a learner who knows 'very', 'low', and 'frequency' can infer it refers to a frequency that is very low. However, the specific technical sense (the radio band 3–30 kHz) is domain-specific and not fully predictable from the constituents alone, so full understanding requires prior exposure or subject knowledge.
Etymology
The term very low frequency names radio waves that repeat only a few times each second. The words very, low, and frequency show that the waves are slow and rare, and because these waves are very long they can travel far and even go under the sea, so they are used for 'long-distance communication' like talking to submarines.
