Hello there! I'm an expert in English grammar and language usage. I'm here to help you understand the nuances of English possessive forms. Let's dive into the question you've asked about the singular possessive form of the noun "teacher."
When it comes to forming possessive nouns in English, there are a few rules to follow. The singular possessive form of a noun indicates that something belongs to or is associated with that noun. For example, if we're talking about the book that belongs to a teacher, we would use the singular possessive form of "teacher."

Now, let's address the specific case of the word "teacher." If the word "teacher" is singular and ends in an "s" sound, the possessive form can be made by adding an apostrophe followed by an "s" ('s). This is because the "s" at the end of "teacher" is not a letter "s," but a part of the pronunciation that signifies a plural noun. However, when we're talking about a singular noun that ends in an "s" sound, we still follow the general rule of adding 's to show possession.

So, the singular possessive form of "teacher" would be "teacher's." As in, "The teacher's book is on the desk." Here, "teacher's" indicates that the book belongs to the teacher.

Now, let's look at the reference content you've provided. It mentions two options for forming the possessive of a singular noun that ends in an "s" sound:

1. Adding an apostrophe and an "s" ('s): This is the more common and traditional approach. It is used when the "s" at the end of the word is not part of the word itself but is a plural marker. For example, "The bus's brakes are faulty."

2. Adding just an apostrophe: This is an alternative that some people use, especially when the word ends in an "s" sound that is not a plural marker. For example, "Carlos' pen is blue." In this case, "Carlos" ends in an "s" sound, but it is not a plural noun, so just an apostrophe is added.

For the word "teacher," since it is a singular noun and ends with an "s" sound that is not a plural marker, you could technically use either form. However, the more traditional and widely accepted form is to add an apostrophe and an "s" ('s), making it "teacher's."

In conclusion, the singular possessive form of "teacher" is "teacher's," and it is formed by adding an apostrophe followed by an "s" after the word, indicating possession or association.

Now, let's proceed to the next step as per your instructions.
