Question

What is the difference between "Annyeonghaseyo (name) imnida" and "Annyeonghaseyo jeoneun (name) imnida ?

Answer 1

"Annyeonghaseyo ___ imnida" and "Annyeonghaseyo jeoneun ___ imnida" both have different definitions.

"Annyeonghaseyo? Jeoneun Bob* - imnida" is the formal way of introducing yourself in Korean (to your parents, teachers, etc).

When you introduce yourself casually, you take out  "jeoneun".

"Annyeonghaseyo? Bob - imnida."

*Bob (name) is used as an example.
