Morphology
Tesla + coil
The noun 'coil' clearly signals a wound wire component, and the proper name 'Tesla' links the item to Nikola Tesla (or the Tesla brand) and thus to electrical technology, so a learner who knows both constituents can reasonably infer it is an electrical coil. However, the precise technical sense (a step-up transformer producing high-frequency, high-voltage discharges) is specialized and not fully predictable from the parts alone, so full understanding requires domain knowledge or exposure.
Etymology
Tesla coil is named after the inventor Nikola Tesla, who used a wrapped wire called a coil to make bright, lightning-like sparks in his shows. Because these coils produced 'high voltages' and dramatic sparks, the name now means a device that makes very strong electric sparks.
