Jr

The word “Jr” means abbreviation for "junior," used after a name to distinguish a son from a father who shares the same name. In plain terms, used after a name to mark someone as the younger of two family members sharing a name.

Here is “Jr” used in a sentence: “Martin Luther King Jr. was named after his father.”

“Jr” is an adjective.

“Jr” is a fairly common word in modern English.

Jr is short for 'junior' and is placed after a man's name to show he is the son of a father with exactly the same name. For example, if Robert Smith names his son Robert Smith, the son becomes Robert Smith Jr. It helps distinguish the two people in writing and speech.

Jr, or junior, marks the son, while Sr, or senior, marks the father when both share the same full name. The father usually only takes 'Sr' once his son with the matching name comes along. So Robert Smith Sr is the father and Robert Smith Jr is his son.

Jr is used when a boy is named directly after his own father. The suffix II, meaning 'the second,' applies when someone is named after another relative, such as a grandfather or uncle, rather than his father. Both signal a shared name across generations, but they point to different family relationships.
