Boris Johnson, the Mayor of London appeared on BBC Newsnight. At about the 5min mark the interviewer asked the Mayor to review three clips of other British politicians of various parties. It’s interesting to watch Johnson as he views these clips, his reaction is priceless.
More importantly his message about what was wrong with all three clips is a critical lesson. Simple language is more effective. In the words of Boris Johnson, using endless latinate words is a clue to the intent of the speaker and that intent isn’t positive.
Speak simply. Use plain English.
