Morphology
fat + finger
The phrase combines the literal words 'fat' and 'finger' in a metaphorical way: a finger that is too large suggests accidentally hitting the wrong key, so a learner who knows the constituents can plausibly infer it refers to an input error. However, the shift from a physical description to the conventionalized technical sense ('a clumsy keystroke/mistake') is somewhat domain-specific and not fully predictable without contextual exposure, so it is not fully transparent.
Etymology
The expression fat finger may come from a simple picture: a person with a fat finger hitting more than one key or button by mistake. That's why today it means 'a clumsy mistake' when someone presses the wrong key or button.
