- Indeed, one of Thomson's major contributions was his recognition that a good vacuum is required to produce an electrostatic field inside the tube, a field that can deflect the electrons making up the cathode ray.

Morphology
The noun phrase is compositionally built from 'electrostatic' (pertaining to static electricity) and 'field' (a region in which forces act), so a learner who knows both constituents can infer it denotes the region around static charges where electric forces operate. This is a straightforward technical compound following normal adjective + noun formation and has no idiomatic or metaphorical shift, making it easily interpretable across languages with similar scientific vocabulary.
Etymology
The term electrostatic field comes from the simple image of an invisible space around a charged object, like a rubbed balloon that makes your hair stand up. The word electrostatic means 'electric but not moving' and field means the space around it, so the phrase refers to the area where charges 'push or pull' other charges.
