Every contemporary adult speaker of American English is sure to know what a “buzzword” is, which is commonly defined (e.g., by Merriam Webster Unabridged Dictionary Online)as
1: an important-sounding and often technical word or phrase associated with a special group or activity and used chiefly to impress others;
2: a word enjoying a popular vogue.
However, the adjective ‘buzz’ can also be applied to phrases. Such is the case of the buzz phrase “in terms of,” which is heard ad nauseum by speakers on both sides of the Atlantic instead of “regarding,” “on,” etc. as a way of specifying the domain of whatever verbal material precedes it. Accordingly, one incessantly hears such locutions as “My opinion in terms of that action . . .” instead of the traditional “My opinion regarding/on that action,” etc.
One is tempted to explain this development as yet another instance of American English’s penchant for hypertrophy.
