Rule 1.2: Use approved words as the specified part of speech

What a checker looks for

A clear deviation from the rule.

• Flag a word approved as one part of speech (e.g. a noun or adjective) being used as a different part of speech (e.g. as a verb) — for example 'test' is an approved noun but not an approved verb, so 'test the system' is a violation.
• Flag adjectives used as verbs (e.g. 'dim the lights') when the dictionary only approves the adjective form.

What this rule does not cover

• A word approved as more than one part of speech (e.g. 'clean' as both verb and adjective) is compliant either way; its position in the sentence shows which is being used.

How to fix it

Reconstruct the sentence so the word is used only in its approved part of speech — often this means turning a verb usage into a noun phrase ('do the leak test of the system' instead of 'test the system') or finding an approved verb with the same meaning ('make sure the valve can operate' instead of 'make sure the valve is operable').

Constraints on the fix

• Preserve the original instruction's meaning exactly.
• If the straightforward replacement changes meaning, use a different word or sentence construction instead.
