Expert writing Tips
Best practice
When describing food, use "rancid" to specifically indicate the unpleasant taste or smell resulting from fats or oils decomposing, rather than general spoilage.
Common error
Avoid using "rancid" to describe non-food related unpleasantness when a more appropriate term like "offensive" or "disagreeable" might be more fitting. While "rancid" can be used metaphorically, it is most effective when directly related to spoiled fats or oils.
