SYNERGY

Synergy can be defined as “increased effectiveness, achievement, etc., produced as a result of combined action or co-operation.”

Until the late 1950s, the term was probably most commonly seen in a scientific context to describe the interaction of organs or nerves. Now it is common in corporate-speak and popular as a brand name for various businesses and products.

Synergy is so popular online that it brings up 50,500,000 results. Here are some of them:

Synergy HomeCare (cleaning service)
Synergy Software (makers of a graphing and analysis program)
Synergy Sport Tech (Fantasy Basketball App)
Synergy Realty Group (real estate agency)
Synergy (something to do with using iTunes)
Synergy Cancer Center
Synergy Church
Synergy Healthcare

This is how the word is used in the corporate world :

Eczacibasi and Burgbad expect synergy potential in the areas of international sales and distribution as well as innovation management.

Notice that in every one of these quotations, the noun synergy is preceded by the verb expect. Although in some contexts, synergyconveys a specific meaning, in the jargon of business, the closest definition is, “an as-yet unknown result that we hope will prove profitable.”

Spelled synergie in the earliest OED citation (1632), the word referred to the cooperation between human will and divine grace: “In the virtue of which synergy and co-partnership with Christ and with God, as he saves, so we save; as he forgives sins, so we forgive them.” [Spelling modernized.]

In the 19th century, synergy acquired a use in physiology to refer to the interaction of body parts, such as “the relation of action between the glottis and the muscles.”

A writer in 1917 finds synergy an apt term to describe the way that the presence of two ions “in some way increases the action of both.” In a 2008 citation, the word synergy is used in the context of drug interactions: “Very little is known about how the evolution of resistance is affected by the nature of the interactions—synergy or antagonism—between drugs.”

Synergy registers on the Ngram Viewer in 1827, but doesn’t make much of a showing until the 1960s.

I agree with David Lehman who comments in the Oxford American Writer’s Thesaurus as to the ineffectiveness of the wordsynergy in the context of business mergers: “Some words don’t work. Synergy is one of them.”

Lehman admits that—theoretically—the usage makes sense in a business context, but points out that the concept is flawed because the mergers that are supposed to result in synergy “seldom go according to plan” and “that is surely why you hear the word only in the business news, among executives and mouthpieces for whom hope springs eternal.”
