Mothers and fathers used to bring up children: now they parent. Critics used to review plays: now they critique them. Athletes podium, executives flipchart, and almost everybody Googles. Watch out — you’ve been verbed. The English language is in a constant state of flux. New words are formed and old ones fall into disuse. But no trend has been more obtrusive in recent years than the changing of nouns into verbs. “Trend” itself (now used as a verb meaning “change or develop in a general direction”, as in “unemployment has been trending upwards”) is further evidence of — sorry, evidences — this phenomenon.
