widget
Synonym discussion
Sense: noun/1
All four words refer to a physical object, tool, or piece of equipment, but they differ in tone and purpose. 'Gadget' is the closest neutral synonym and suggests a small, cleverly designed tool — it lacks the 'placeholder for an unknown name' function that widget carries. 'Thingamajig' is a deliberate placeholder, even more informal than widget, and often implies the speaker has no interest in learning the real name. 'Device' is more formal and precise; you would use it in product manuals or technical descriptions rather than in casual speech. 'Contraption' suggests something that looks complicated, oddly built, or unreliable, so it adds a judgement that widget does not. For everyday conversation when you simply cannot recall the name of a small tool, 'widget' or 'thingamajig' are the most natural choices, while 'gadget' works when you want a neutral term without the 'missing name' idea.

Etymology
The origin of 'widget' is uncertain, but it is most commonly believed to be a blend formed from 'gadget' and 'whatchamacallit' (a placeholder word for an unknown thing). The word first appeared in American English around the 1920s and was adopted by economists in the mid-20th century as a standard term for a hypothetical manufactured product in textbook examples. The computing sense (software panel) emerged in the 1990s with the rise of graphical user interfaces.
