Nancy was taking the next flight to Paris so she had to cut short the interview.
Would you explain the following phrase?
Had to cut short the interview.
She was obliged to make the interview shorter than expected.
What this means is that Nancy was on a tight schedule for her flight, she would have missed her flight if she wasn't quick enough.
Had to cut short the interview means that due to her busy schedule, she had to make sure that the interview didn't take too long or that the interview was cut short (in terms of time) as otherwise she would have missed her flight.
