Final answer:
Common errors with apostrophes involve confusion between possessive nouns and contractions. Possessive apostrophes indicate ownership, while contractions use apostrophes to denote the omission of letters. Mistakes can also occur with homophones like its/it's or their/they're.
Step-by-step explanation:
Common errors associated with apostrophes often arise when distinguishing between possessive nouns and contractions. Possessive apostrophes are used to show ownership and should be added to the singular form of the word, even if it ends in -s (e.g., the owner's insurance), and after the -s in plural nouns (e.g., The parents' house). However, making a noun plural does not require an apostrophe (e.g., apples, not apple's).
When forming contractions, apostrophes replace omitted letters (e.g., don't for do not, it's for it is). Confusion often occurs with homophones, such as its (possessive) and it's (contraction of it is), or their (possessive) and they're (contraction of they are). Ensuring proper usage of apostrophes is crucial for clear communication.
