TITLE: What are better words to use in an article than "obvious"?
QUESTION [19 upvotes]: I've heard often than it is ill-form to use the word "obvious" in a research paper. I was hoping to gather a list of less offensive words that mean generally the same thing. 
For example, one that I can think of is the word "direct". 
So instead of saying "...obviously follows from lemma 2.3..." you'd say "...this proof directly follows from lemma 2.3...".

REPLY [3 votes]: Don’t try to find a synonym, that doesn’t solve the problem that “obvious” has. The problem is that when you feel the need to point out that a connection is obvious, it probably isn’t. Don’t say it’s obvious, make it obvious. Or, if it’s really obvious, just state it. No need for a word such as “clearly” or “evident”.
Ironically, this seems rather obvious to me but all the other answers missed it, and instead suggest synonyms which, as I’ve said, suffer from exactly the same problem.
