[Grammar] a/an or a zero article

[4ania4]

Dear Teachers,

I think you should say/write

a well-organised knowledge in the field of fundamentals of functional analysis.

because it is specific.

However I am not sure as I can see

knowledge of/about: Solicitors should possess detailed knowledge of certain aspects of the law.


in Macmillan Dictionary.

Isn't it specific either?

Thank you for your help,

What is the rule

"a well-organised knowledge in the field of fundamentals of functional analysis" I don't find this at all natural.

 

[5jj]

knowledge of/about: Solicitors should possess detailed knowledge of certain aspects of the law.

This is correct as it is. It's also possible with the indefinite article.

I agree with bhai; I find the first sentence unnatural. Does the writer simply mean '(a) sound knowledge of the fundamentals of functional analysis'?

 

[4ania4]

Thank you for drawing your attention to the choice of an adjective. I want to say that the student knows a lot on the fundamentals of functional analysis and his/her knowledge is reliable. I would like to find the adjective which would sound more formal - either sound or thorough?

 

[5jj]

It's not a matter of formality. A sound knowledge is less thorough than a thorough knowledge.

 

[4ania4]

I see. So I need "thorough". One more word came to my mind: comprehensive. My last question: Is comprehensive more or less the same as thorough?
I'm really grateful your help.
Have a nice evening
