There are lots of examples where the definite article is used with the pronoun 'someone', for example:
I never knew you were the someone waiting for me. (Source.)
How about a little something special for the someone who truly deserves it?
For all creative people we suggest to place the someone works (poems, stories, songs, figures, an art photo, etc.) on this site.
I wonder what does 'the' mean in contexts like these and are there any other cases when we can use the definite article before a pronoun? Are these examples grammatically correct?
