Morphology
reticular + activating + system
The compound parts ('reticular' = netlike, 'activating' = causing activation, 'system' = ensemble) let a learner infer this is a system with a netlike structure that causes or supports activation, so there is some compositional clue. However, the specific technical referent — the brainstem mechanism that regulates alertness and arousal — is specialized and not fully predictable from the constituents alone, so prior domain knowledge is needed.
Etymology
Reticular activating system comes from words that mean a net and an alarm: reticular means 'net-like' and activating system is like something that turns things on. Imagine a net of nerve cells in the lower part of the brain that acts like a small alarm to wake and keep you alert, so the phrase names the brain part that controls 'alertness' and being awake.
