If you want to get your point across in an email, blogging, or just in a basic conversation, stay away from the highbrow language. It might make you look smart, but when you do use these words you increase the odds of people not knowing what the hell you are saying and your message will be lost in translation.
It takes a rare bird to stop someone and say, “What does X mean?” Usually we are too afraid to say anything, so then we will continue listening without truly understanding what the speaker is talking about.
Words to never use:
Orthogonal, instead just “independent”
Immaterial, instead use “not relevant”
Verticals, instead “specific group or market”
Inflection Point, instead use “turning point”
If the word is not being used in a fifth grade english class the odds of the word being understood goes down significantly.
