Surface Forms

Morphology

great + Caesar's + ghost

The phrase literally combines an intensifier ('great') with a famous proper name's possessive and 'ghost', so a learner who knows the words could plausibly infer an emphatic exclamation invoking surprise or shock. However, the expression is a conventionalized interjection tied to a cultural/historical reference (Caesar) and functions as a fixed formula rather than a compositional description, so the exact pragmatic use is not fully predictable without prior exposure.

Etymology

Great Caesar's ghost may come from the dramatic idea of the old Roman leader Caesar suddenly appearing as a ghost, a powerful picture of surprise. That's why people used the phrase to show 'surprise', 'shock', or 'disbelief'.
