- Match the Context: Is this for an academic paper, a text message, or a business report? Use formal words like “venal” for a paper, and informal words like “shady” for a text.
- Match the Tone: Are you describing a minor offense or a major crime? Use a mild word like “improper” for a minor issue and a strong word like “depraved” for a major crime.
- Check the Intensity: Don’t overstate a problem. Saying someone is “depraved” is much stronger than saying they are “untrustworthy.”
- Think About the Reader: Will your reader understand the word? If not, choose a simpler synonym like “dishonest.”
- Check if It’s an Exact Match: “Bribery” is related to corruption, but if you’re talking about a corrupt judge, you want a word like “venal,” not “bribery.”

- Using a formal word in casual writing: Don’t say “I find his behavior to be duplicitous” in a text to a friend. Say “He’s so two-faced.”

- Replacing “corrupt” without checking the meaning: Don’t use “rotten” to describe a corrupt computer file. Use “corrupted” or “damaged.”

- Making the sentence sound unnatural: Read your sentence aloud. If it sounds awkward, change it. “The corrupt data” is natural. “The nefarious data” is not.
