My pet peeve math term is "clear". A long time ago I thought could teach myself group theory by buying the Springer group theory book and reading it from chapter 1, 1 page at a time. But I was blocked within the first 5 pages because the axioms and first few proofs kept saying how "clear" it was that all the results followed. Unfortunately, it was not "clear" to me :(

I had a calc prof who was in the middle of a lecture, "...and as any fool can see, X is..." He stopped, turned around, and said, "You know, sometimes when I say, 'It is intuitively obvious', or, 'As any fool can see', I realize it may not be intuitively obvious, and any fool may not be able to see. But as any fool can see, X is..."

> the Springer group theory book

I am skeptical that this uniquely identifies a book (unless you mean the book "Linear Algebraic Groups" by the author called Springer, rather than the publisher called Springer, in which case it's definitely not the way to start learning group theory!).

It was the yellow Springer publishing book. Happened 20+ years ago now, cannot recall the author. IIRC the title was "a course in the theory of groups".

This one, probably: https://link.springer.com/book/10.1007/978-1-4419-8594-1

It’s a graduate-level text, to be fair.
