What part of speech are the words 'their' and 'out' in this sentence? "These cost cutting measures work to their disadvantage'. 'Five reasons stand out'
"These cost-cutting measures work to their advantage."
"These" is a pronoun acting as an adjective telling us what measures.
"cost-cutting" is two words acting as one (hence the hyphen) telling us what kind of measures we have. It is an adjective.
"measures" is a noun. It is the subject of the sentence.
"to" is a preposition, the object of that preposition is "advantage". Therefore, "advantage" is a noun.
"their" is a pronoun. It is always a plural possessive pronoun.
"Five reasons stand out."
"Five" is an adjective telling you about "reasons".
"reasons" is a noun and the subject of the sentence.
"stand" is the verb.
"out" is a noun. It is acting as the direct object in this sentence. To find the direct object, find the subject and verb and ask the question "who or what". If you have an answer, you have a direct object. "Reasons + stand + who/what" = "out".
Remember that different words can function as different parts of speech depending on context, so you must always ask yourself, "What is this word telling me more about in the sentence?" It is easier to determine parts of speech once you figure out the subject and the verb of the sentence. Everything else is extra and is telling you something more about the subject or verb, usually.
