Can you please help me identify the relationship of the subordinate clause with the main clause in this sentence:
(1)He was so happy that he burst into a song.
that he burst into a song - adverb clause of result, modifying ....??
Similarly,
(2)He is as proud as a peacock.
as a peacock - adverb clause of comparison of degree, modifying ....??
(3)Though he is poor, he is honest.
though he is poor - adverb clause of concession, modifying ....??
I want to know how to identify the relationship.
