In the American Heritage Dictionary, one of the definitions of the word lightweight is
A person of little ability, intelligence, influence, or importance.
When it comes to denote having certain features or qualities, I get lost when I want to determine which way to convey it. I often find myself asking questions like "Should I say of or with or that has or a gerund: possessing?" In the definition of the word lightweight, I have seen that almost in all other dictionaries they used the preposition of after the word person, and I was wondering why they used of instead of the following:
A person with little ability, etc.
A person who has little ability, etc.
A person possessing/having little ability, etc.
A person whose ability, etc is little
A person who exhibits/displays little ability, etc.
And the same ways of saying the above arises when I say other things such as:
A matter of/with/etc no importance.
A person of/with/etc 30 years' experience.
Could please help me lessen this paradox of choice?
