Etymology: "Queror" is the Latin dictionary form of a verb meaning "to complain" or "to lament." It is a deponent verb, which means it looks passive but works as an active verb. Its principal parts are "queror, queri, questus sum," and the form "queri" appears in the Latin infinitive. The verb's root also produced the English adjective "querulous," meaning fretful or full of complaint, which comes from the Latin "querulus." Because "queror" resembles "query," readers sometimes assume the two are related, but "query" comes from a different Latin verb, "quaerere," meaning "to seek" or "to ask."
