Answer:
The correct plural words are oxcarts, alleys, beliefs, and libraries.
Step-by-step explanation:
1. Terry -> Terries
The plural of the name Terry is Terrys, not terries. Although, if we were referring to a terry cloth, the plural terries would be correct.
2. Oxcart --> Is the plural oxencart or oxcart?
The plural form of oxcart is oxcarts. Although, the plural of ox is oxen. This is because we are referrin to the cart not the oxen. Oxencart is not correct.
3. Alley --> Alleys
This is correct. We have one alley or multiple alleys. In this case, the "y" does not change to "ies."
4. Belief --> Beliefs
This is correct. However, belief can be a countable or an uncountable noun. Used generally, the plural of belief will be beliefs. However, sometimes the plural of belief is also belief. This is in reference to a collection of belief or different types of belief.
5. Library --> Libraries
This is correct. The plural of library is libraries. In this case, the "y" is changed to "ies." Librarys is not a word.
