Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Using “on son” as a relationship phrase

English does not normally use on directly before son to show relationship.

✕ He is on my son. ✓ He is my son.

Confusing “of” and “to”

Use of for family relationships and to for direction or recipients.

✕ a letter of my son ✓ a letter to my son

Missing the article or possessive

Son usually needs a determiner in specific references.

✕ I spoke to son. ✓ I spoke to my son.
