Examples:
- Their son starts school today.
- Her son works in another city.
- He is the eldest son in the family.
Unlike boys, sons identify family relationships. A son can be a newborn baby, a teenager, or an older adult. Words such as child, offspring, and descendant are related in meaning, but they are not interchangeable with son in every sentence.
