Morphology

eight + ball

The phrase is compositionally built from the numeral 'eight' and the noun 'ball', so a learner who knows both words will readily infer it refers to the ball marked number eight. This noun–number combination is a common, cross-linguistic compositional pattern (i.e. ‘the eight ball’ = the ball numbered eight), so the referent is transparent even if game-specific rules about pocketing are separate encyclopedic knowledge.

Etymology

Eight ball comes from the game of pool: it is the black ball marked with the number 8 that players must pocket 'last'. Because that one ball decides who 'wins', the eight ball became a clear image for the final, deciding shot.
