4. 'Doing the needful'
Try to avoid using the phrase "do the needful." It went out of style decades ago, about the time the British left.Using it today indicates you are a dinosaur, a dinosaur with bad grammar.
You may use the phrase humorously, to poke fun at such archaic speech, or other dinosaurs.
“Will you do the needful?”
“Of course, and I’ll send you a telegram to let you know it's done too.”
