prankster

The word 'prankster' is a relatively modern English compound, formed from the native word 'prank' and the agent suffix '-ster'. 'Prank' itself emerged in the 16th century, its origins somewhat obscure but likely connected to Germanic roots implying ostentation or playful adornment, which evolved to mean a mischievous trick. The suffix '-ster' has a long history, originating from Old English '-estre', a feminine agent-forming suffix (as in 'spinster'), which over time lost its gendered specificity. Thus, a 'prankster' is, quite literally, 'one who performs pranks', a playful agent of mischief, its formation following a classic and transparent English pattern for creating agent nouns.
