What happened: English meaning/origin/usage Q&A answered four vocabulary queries

A language-learning Q&A column answered reader questions with definitions, pronunciation guidance, usage examples, and short origin notes. The Q&A covered four items: “sting operation,” the difference between “while” and “whilst,” “psephologist,” and the idiom “to hit the sack.”

1) “Sting operation” and informal “sting”

“Sting operation” was defined as a planned law-enforcement scheme that uses undercover work to entrap a criminal. The Q&A also noted an informal wider use of “sting,” where “sting” can mean cheating or overcharging.

2) “While” vs “whilst” (meaning, style, pronunciation)

The Q&A stated that “while” and “whilst” are effectively interchangeable in meaning. It added a style note: “whilst” is somewhat old-fashioned and is more common in British English. The Q&A also included pronunciation guidance and example sentences using both forms.
