Expert writing Tips

Best practice

When using "are not introduced", ensure the context clearly specifies what is lacking introduction to avoid ambiguity. For example, "The new safety protocols are not introduced in this version of the software" provides clarity.

Common error

Avoid stringing multiple clauses together where "are not introduced" appears, as this can lead to convoluted sentences. Break down complex ideas into smaller, more digestible statements for better clarity. For example, instead of saying "Because the variables are not properly defined and the assumptions are not introduced, the model fails", it's clearer to say "The variables are not properly defined. The assumptions are not introduced. Consequently, the model fails."
