Here's why:
* Suffix "-ment" creates nouns: The suffix "-ment" is often added to verbs to create nouns that represent the action, state, or result of the verb.
Examples:
* Verb: move -> Noun: movement (the act of moving)
* Verb: manage -> Noun: management (the act of managing)
* Verb: improve -> Noun: improvement (the result of improving)
Exceptions:
While most words ending in "-ment" are nouns, there are some exceptions. Some words ending in "-ment" can be adjectives or adverbs:
* Adjective: momentary (lasting for a short time)
* Adverb: frequently (often)
To determine the part of speech:
* Consider the context in which the word is used.
* Look for the grammatical function of the word in the sentence.
* Check a dictionary for the word's definition and part of speech.
