WORD NOTE focus Focus is now the noun of choice for expressing what people used to mean by concentration (•Sampras's on-court focus was phenomenal) and •emphasis (•Our focus is on satisfying the needs of our customers). Adjectivized, it seems often to serve as an approving synonym for driven or monomaniacal:•He's the most focused warehouse manager we've ever had. As a verb, it seems isomorphic with the older to concentrate:•Focus, people! ; •The Democrats hope that the campaign will focus on the economy; We need to focus on finding solutions instead of blaming each other ; etc. Notice, with respect to those last two sample sentences, how the verb phrase to focus on can take as its object either a thing-noun ("economy") or an ing-word ("finding"), and how its grammar is slightly different in these two cases. With a noun, to focus on means "to concentrate attention or effort on," i.e., the direct object is built right into the verb phrase; but with ing-words it means "to direct toward a particular goal"—there's always a direct object like "attention/efforts/energies" that's suppressed but understood, and the ing-word functions as an indirect object. Given the speed with which to focus has supplanted to concentrate, it's a little surprising that nobody objects to its somewhat jargony New Age feel—but nobody seems to. Maybe this is because the word is only one of many film and drama terms that have lately entered mainstream usage, e.g., to foreground (= to feature, to give top priority to); to background (= to downplay, to relegate to the back burner); scenario (= an outline of some hypothetical sequence of events), and dialogue. — DFWConversational, opinionated, and idiomatic, these Word Notes are an opportunity to see a working writer's perspective on a particular word or usage. |
