A long sentence in which the completion of the syntax and sense is delayed until the end, usually after a sequence of balanced subordinate clauses. The effect is suspense, because the reader is compelled forward to the end of the sentence to discover the outcome. Many Victorian writers (two particularly verbose examples are Charles Dickens and Henry James) employed this type of sentence.
Whenever you go outside, into the daylight, and see the blue sky, and the birds flying high above, you must be inspired.
This is the opposite of a loose sentence.
