The Dictionary: what math lecturers say and what they mean by it.

* Clearly: I don't want to write down all the "in-between" steps.

* Trivial: If I have to show you how to do this, you're in the wrong class.

* It can easily be shown: No more than four hours are needed to prove it.

* Check for yourself: This is the boring part of the proof, so you can do it on your own time.

* Hint: The hardest of several possible ways to do a proof.

* Brute force (and ignorance): Four special cases, three counting arguments and two long inductions and a partridge in a pear tree

* Soft proof: One third less filling (of the page) than your regular proof, but it requires two extra years of course work just to understand the terms.

* Elegant proof: Requires no previous knowledge of the subject matter and is less than ten lines long.

* Similarly: At least one line of the proof of this case is the same as before.

* Two line proof: I'll leave out everything but the conclusion, you can't question 'em if you can't see 'em.

* Briefly: I'm running out of time, so I'll just write and talk faster.

* Proceed formally: Manipulate symbols by the rules without any hint of their true meaning.

* Proof omitted: Trust me, It's true.

* Obviously: I hope you weren't sleeping when we discussed this earlier, because I refuse to repeat it.

* Recall: I shouldn't have to tell you this, but for those of you who erase your memory tapes after every test...

* WLOG (Without Loss Of Generality): I'm not about to do all the possible cases, so I'll do one and let you figure out the rest.

* It can be easily shown: Even you, in your finite wisdom, should be able to prove this without me holding your hand.

* Sketch of a proof: I couldn't verify all the details, so I'll break it down into the parts I couldn't prove.

* Canonical form: 4 out of 5 mathematicians surveyed recommended this as the final form for their students who choose to finish.

* TFAE (The Following Are Equivalent): If I say this it means that, and if I say that it means the other thing, and if I say the other thing...

* By a previous theorem: I don't remember how it goes (come to think of it I'm not really sure we did this at all), but if I stated it right (or at all), then the rest of this follows.

* Let's talk it through: I don't want to write it on the board lest I make a mistake.

* Quantify: I can't find anything wrong with your proof except that it won't work if x is a moon of Jupiter (Popular in applied math courses).
