Select the word that is spelled INCORRECTLY.

Concept

Spelling questions test whether each word matches its standard dictionary form. The reliable method is to recall the word's root and the suffix pattern it uses, then check each given form against that pattern letter by letter. A single wrong vowel or consonant makes the form non-standard.

Application

Apply the root-and-suffix test to each word given here:

• “Monarchy” comes from monarch + -y; this matches the standard dictionary spelling.

• “Monetary” is formed from the Latin root moneta and the adjective ending -ary; this matches the standard dictionary spelling.

• “Monastery” (from Latin monasterium) is a standard dictionary word; its accepted spelling ends in -ery, so it is spelled correctly.

• “Momentery” is built on the root moment; the standard adjective form takes the ending -ary, giving “momentary”. The form written here uses -ery, so it does not match the dictionary spelling.

Result

Three of the four words match their standard dictionary spelling, while “Momentery” departs from it; the correct adjective from “moment” is spelled “momentary” (ending in -ary, not -ery). Therefore “Momentery” is the word spelled incorrectly.

Cross-check

Standard dictionaries (Merriam-Webster, Cambridge) list “momentary” as the only accepted spelling and have no entry for “momentery”, confirming the result.
