In the course of my travels, I met a good-natured old gentleman, (a) who was born in the village (b) where my parents lived (c) before they came to America.

Here gentleman (a complement in the main clause) is modified by the adjective clause who was born in the village (a). Village, in clause a, is modified by the adjective clause where my parents lived (b). Lived, the predicate verb of clause b, is modified by the adverbial clause before they came to America (c).

Thus it appears that a is subordinate to the main clause, and that b, in turn, is subordinate to a, and c to b. In other words, the three clauses (a, b, c) are united to make one complex clause,—who was born in the village where my parents lived before they came to America. This clause, taken as a whole, serves as an adjective modifier describing gentleman.

523. Further examples of the successive subordination of one clause to another may be seen in the following sentences:—

Note. The method of forming complex clauses by successive subordination, if overworked, produces long, straggling, shapeless sentences, as in the following example from Borrow:—“I scouted the idea that Slingsby would have stolen this blacksmith’s gear; for I had the highest opinion of his honesty, which opinion I still retain at the present day, which is upwards of twenty years from the time of which I am speaking, during the whole of which period I have neither seen the poor fellow nor received any intelligence of him.” A famous instance of the use of this structure for comic effect is “The House that Jack Built.”

SPECIAL COMPLICATIONS

524. The processes of coördination and subordination ([§§ 514–523]) may be so utilized in one and the same sentence as to produce a very complicated structure.

Examples of such sentences are given below, for reference ([§§ 525–526]). Their structure, however elaborate, is always either complex or compound complex.
