What is of interest in the interaction of relativization and topicalization is that it is not possible for the two rules to apply in a single clause and produce a topic within a relative clause. Consider the following Korean sentences.
(1) *i salam-i (i chaek-un Chelswu-ka cwun) Yenghi-ita.
this man SM this book TOP SM gave be
'*This is Yenghi whom the book Chelswu gave to.'
(2) '*(Yenghi-nun Chelswu-ka manna-n) hakkyo-ka phakoytoYessta.
TOP SM met school SM was-detroyed
'*The school which Yenghi Chelswu met in was destroyed.'
(3) *(ku totwuk-un caphi-n) swunkyeung-i sang-ul patassta.
the thief TOP was-caught policeman prize received.
'*The policeman whom the thief he was caught by was awarded.
