I always advise writers to be concise. This is not easy and I write redundant words too if I’m not careful.
In an earlier post, I wrote “past experience” when “experience” could have sufficed because experience is something that has happened.
Here are other examples:
bright flash of light
huge skyscraper
Free gift
Old antiques
Actual facts
Basic fundamentals
Add up
Brief summary
Exact same
Of course in a narrative story, sometimes, we deliberately use synonyms to emphasize a fact or make the story interesting.
For instance: “I have an itsy bitsy teeny weeny tiny little rant,” said the boy.
But that’s a tip for another day.
Can you think of other redundancies?
