Morphology
The image of 'dig' + 'one's own' + 'grave' evokes the idea of causing one’s own burial, so a learner who knows the words will likely infer self-inflicted harm or downfall. However, the expression is a metaphorical extension (not literal) and the precise idiomatic nuance — causing one’s failure or downfall rather than literal death — is not fully predictable without exposure, so it is only partly transparent.
Etymology
The idiom dig one's own grave creates a clear image of someone with a shovel actually digging their grave, so they cause their own end. That's why the phrase means 'to do something that causes your own failure or downfall'.
