Do you recall the 1950s’ cigarette commercial jingle that went like this: “Winston tastes good, like a cigarette should”? I know this dates me, but I do. I also recall being told in school that this sentence is grammatically incorrect. If you’re like me, you struggle a bit with like and as. Why? Because in modern usage, using like instead of as has become almost accepted and integrated into modern language. On Garner’s scale of 1-5 (Garner’s Modern American Usage), with 5 indicating a word or phrase has become “universally accepted,” he rates this usage as a 4.
Grammatical purists insist that using like as a conjunction rather than a preposition breaks the rule. The rule they are referring to states that like is a preposition that functions as an adjective, not an adverb, and must be followed by a noun or pronoun. As or as if is a conjunction. Conjunctions connect clauses. Hence, grammarians cringed at the ad claiming that in the offending line, like functions as a conjunction joining an independent clause—”Winston tastes good”—with a subordinate clause—”a cigarette should [taste].”
When like is used as a preposition it means “similar to” or “typical of.” Notice how you could replace like with similar to in the following examples:
- Alice looks like her mother.
- Her dress looked like an original Donna Karan.
A common mistake is using like when as if is what’s called for:
- It looks
like as if the government shutdown is about to come to an end.
- Joan looks
like as if she has lost her best friend.
In both examples, as if functions as a conjunction connecting two independent clauses. However—and do keep this in mind—when writing fiction, there are occasions (sometimes a lot of them!) when a character is going to think and speak inaccurately, based on who he is, his background, his education. In many manuscripts I critique and edit, I allow the writer to break this rule because I can tell the characters would break certain grammatical rules. And you must always keep characters in character!
Although grammarians have agreed for hundreds of years that using like as a conjunction is not standard grammar, even The Chicago Manual of Style acknowledges that it is increasingly acceptable in spoken and colloquial usage and advises “consider context and tone when deciding whether to impose standard English.”
