Best practice
Always use the singular form "chain" instead of "chains" with the indefinite article "a" to ensure grammatical correctness. For example, use "a chain of events" instead of "a chains of events".
Common error
Avoid using the plural form "chains" after the indefinite article "a". This error often occurs due to confusion with the plural noun. Remember that "a" indicates a single chain, so the noun should be singular.
