You would not be surprised to learn that I am fascinated with words. It would be a poor job if someone who spends a lot of time writing and public speaking was not interested in the words they use. Our choice of words and vocabulary develops over time and reflects what we read, listen to, watch, etc. Developing a pool of words you can draw from is good, especially if you want to communicate clearly.
Interestingly, we love to express ourselves in short, snappy statements. However, I was intrigued at how often we use memorable three-word phrases that communicate our point clearly. Let me give you some examples:
Black and White
Haves and have-nots
Kiss and tell
Pros and cons
Tried and tested
Flesh and blood
Down and out
