Morphology
nuclear + magnetic + resonance
The constituents 'nuclear' (about atomic nuclei), 'magnetic' (relating to magnetism), and 'resonance' (vibrational/excitation at a frequency) make clear that this is a physical phenomenon involving nuclei and magnetic resonance, so learners can form a rough idea from the parts. However, the precise technical sense—nuclei absorbing and re-emitting electromagnetic radiation and the specific applications in imaging and chemical analysis—requires domain knowledge beyond B1, so the meaning is only partially predictable from the words alone.
Etymology
Nuclear magnetic resonance gets its name from what really happens: tiny atomic parts called nuclei act like little spinning tops that wobble in a magnetic field when you hit them with the right radio wave, and this matching motion is resonance, which makes the nuclei send back a small signal. That's why the name is used for methods that 'listen' to those signals to 'look inside' objects or to study the parts of molecules.
