There definitely are specific conditions for making a sentence elliptical, the objective of which is to streamline the sentence by dropping repetitive words and phrases without changing its meaning or undermining its structural integrity. The ellipsis takes it for granted that the reader would just mentally fill in the gaps with the missing grammatical elements.
As a rule, elliptical sentences consist of two independent clauses, one containing the grammar elements the other has left out. The independent clause with the missing elements is the elliptical clause—an abbreviated adverb clause stripped of its subject and verb.
There are six common forms of elliptical sentences: (1) the routine omission of “that” in modifying clauses, particularly in spoken English; (2) elliptical noun phrases; (3) ellipsis of the verb and its objects or complements; (4) medial or middle ellipsis; (5) ellipsis of clause; (6) ellipsis when words are left out in comparisons using “that” or “as.” These elliptical forms are discussed in “The virtue of elliptical constructions,” a two-part essay that I originally wrote for my English-usage in
The Manila Times in 2005. You can check out the essays by clicking this link to
“Deconstructing and understanding those puzzling elliptical sentences,” which I posted in the Forum last August.
Now, regarding this lead of a lifestyle article, “Having an entrepreneurial spirit is normally the first step but finding the perfect type of business that will suit you can often be the crucial factor in determining success in business,” you asked if it could be rewritten elliptically as follows:
“Having an entrepreneurial spirit is normally the first step in determining success in business but finding the perfect type [of business] that will suit you can often be the crucial factor.”
No, I don’t think the above sentence is a successful elliptical construction. Dropping the words “of business” in the second coordinate clause only fragmented the sentence rather than streamline it. This is because the noun phrase “perfect type of business” in the second clause is actually different from—and not a repetition of—the earlier phrase “success in business” in the first cause. So, when the words “of business” are dropped from the noun phrase “perfect type of business,” it’s no longer clear what the description “perfect type” is referring to. The meaning of the sentence is therefore seriously altered—a clear indication that the attempt to make it elliptical has not succeeded.
I am sure that after you’ve gone over and internalized the six common elliptical constructions discussed in the essay I referred to above, you’d soon become very adept at constructing elliptical sentences.
