Expert writing Tips
Best practice
When intending to express a relationship of equivalence, use grammatically standard phrases such as "as equivalent" or "in terms of equivalency" instead of "as equivalency".
Common error
Avoid using the noun "equivalency" directly after "as" when you need an adjective. "As" typically introduces a comparison, and "equivalent" (the adjective) better serves this purpose.
