Correct spelling, explanation: both princess’s and princess’ are considered correct forms, but they are used in slightly different contexts. Princess’s is used to show possession by a singular noun. You add an apostrophe followed by an -s (‘s) to the noun to indicate that something belongs to or is associated with that singular noun. Princess’ is used to show possession by a singular noun ending in -s when adding another -s after the apostrophe feels awkward or cumbersome. Traditionally, when a singular noun ends in -s, forming the possessive can be done by adding ‘s. However, in cases where the addition of another -s might create confusion or look awkward, it’s acceptable to use just the apostrophe after the -s to indicate possession. This is especially common in names or words with multiple syllables.

Princess’s is the possessive form of princess and follows the standard rule for forming possessives in English for singular nouns. You add an apostrophe and an -s after the singular noun, regardless of whether the noun ends in -s. Princess’ is also correct, but it’s typically used when the singular noun already ends with an -s. In this case, you only add an apostrophe after the -s to indicate possession. Both forms are considered correct, but some style guides or personal preferences may favor one over the other.
