My/Pref/Writing/Use the simpler word

• Eschew obfuscation. Don't use sesquipedalian vocabulary when a simple word exists.
• Beware the curse of words that sound "smart" or that are too specific. You could say "invariant" but you might as well say "something that doesn't change."
• When picking a term, ask yourself, "does this make me sound Highfalutin?" if the answer is yes, try harder to find a plainer way to say it. see also My/Pref/Writing/Use Plain language.
• Avoid Distractors. Don't use a fancy, flowery word like Prose when you just mean text in a file.
• Similar to avoiding distractors, when identifying a word or a term, actively think about how to My/Principle/Dispel Ambiguity. Propose a candidate term, ask how it might produce confusion, then work around it.
