Best practice
Use "not as" to make clear and direct comparisons, ensuring that both elements being compared are explicitly stated to avoid ambiguity. For example: "This book is "not as" engaging as the previous one."
Common error
Avoid using "not as" without completing the comparison. Saying something is "not as good" without specifying what it is not as good as can leave the reader confused. Always complete the comparison for clarity. For example, instead of "The service was "not as" expected", write "The service was "not as" good as expected."
