In #ObsidianMD, I like to have a note for various words/terms, especially if it is easily confused with another word (e.g., ingenious and ingenuous).

In my #obsidian note, I try to start with the root noun, then list any related alternate forms (adjectives, adverbs, etc.), as well as the origin and any notes on Usage (callout). And, of course, the backlinks from other notes (not shown in the screenshot).
