Relative pronouns introduce information referring to the previous part of the sentence (clause). In the sentence:
The kemp that wun the gowd medal wis awfu prood.
The champion who won the gold medal was extremely proud.
The clause 'that wun the gowd medal' provides information relative to the 'kemp'.
These relative clauses are introduced by relative pronouns.
