For a language rich in vocabulary, English has a dearth of what one might call 'function words.' Contrast Japanese, which compared to Indo-European languages, has a much wider variety of words that describe sounds and the way objects seem to feel or look like. Functions words are useful, for they enable you to put a label on a process or concept which would otherwise take many words to explain. They are a sort of shorthand, a code, if you will. Suppose you weren't allowed to the word 'cat'. You would be forced to describe it: a four-legged carnivorous mammalian lifeform. Far simpler just to use the word 'cat.' So here are a list of useful terms:

1) The Goldilocks effect, according to which Venus is too hot, Mars is too cold, and the Earth is just right.

2) The Ben Franklin effect. Franklin once said: 'He that has once done you a kindness will be more ready to do you another, than whom you yourself have obliged.'

3) The Leapfrog effect. This is when people in developing nations adopt new technology and use it in ways that allow them to overtake users in developed nations.

4) The Cocktail effect where one toxin in one product alone may not be very harmful, but when that product is combined with other toxins in various products, the effect could be dangerous.

5) The Dog whistle effect, a term from qualatative research in which someone hears something in a statement or question that researchers do not.

6) The Tomato effect. In the early 18th century, both Americans and the British considered the tomato poisonous despite the fact that Europeans consumed the red fruit and still lived to see another day. Two physicians borrowed this behaviour to the medical world and coined it the “Tomato effect.”

7) The Libertine effect. This definition has yet to be written.
