Etymology: "Mishandler" is about as transparent as English word-building gets: it is "mishandle" with the agent suffix "-er" added, so it names someone who handles things badly. The prefix "mis-" comes from Old English and carries the sense of "wrongly" or "badly," as in "misuse" or "misjudge," while "handle" traces back to Old English "handlian," a derivative of "hand." Put together, the noun describes a person who botches a job through clumsiness, carelessness, or poor judgement. The pattern is productive: English speakers have long attached "-er" to verb phrases with "mis-" to name the person doing the faulty action, which is why similar nouns such as "misdoer" and "mismanager" appear in the same mould. The result is a word whose parts explain its meaning completely, with no surprise hidden in its history.
