Common Mistakes

Using slang in formal writing. Example: A medical report should not say “they hooked up” instead of “engaged in sexual intercourse.
Overusing one phrase repeatedly. Example: Repeating “have sex” five times in one paragraph reduces readability.
Mixing tone within the same piece. Example: Combining “make love” (romantic) with “hook up” (casual) in a formal essay confuses the tone.
Ignoring cultural sensitivity. Example: Some phrases are too direct for certain audiences or platforms.
Confusing euphemisms with vague meaning. Example: “Get together” can also simply mean meeting socially, so context must be clear.
