This semantics issue... It's really a root cause for a lot of trouble. Especially in the cybercommunication era, where people only have words to go by, rather than tone, gestures, pauses, etc... It gets worse when people use abbreviations and acronyms which might stand for 2 completely different things in different regions... We could try this as an experiment... anyone interested in participating, send me a PM with your definition (not a web researched one, or one from a dictionary) for the word theoretical. Next week, I'll write up all the answers I get in a post and include my own. I can guarantee they won't be equivalent. And in some cases we may get wide variances... The same issue arises in everyday discussions (between me and my wife for example)... Especially when someone thinks they know what the other person means, but gets it wrong... not counting the times when a word has several meanings and the wrong one is taken. If there were less communication barriers, the world would be a better place. How many times have tempers flared over a miscommunication? Sometimes even when both sides agree, but they don't realize it.
