Morphology
callback = call (semi-transparent) = back + call
Formed from 'call' + 'back' with a relation to the idea of 'calling back,' but the technical programming sense 'a function invoked later' is domain-specific and may not be derivable by general learners. [Postprocessing: moved 'back' from base_words to prefix]
Etymology
Callback in computing comes from the same parts call + back, meaning 'call' later. Think of leaving your number so someone 'calls you back' — in code a callback is a function or URL a service 'calls' later to deliver a result.
