[tlhIngan Hol] to be sentences with {-bogh} and the {-'e'}

[mayqel qunen'oS]

Read:

{Qun 'oHbe'bogh vIghro''e' wIghajnISbe'}
we don't need to have a cat which isn't a god

What is the role of the {-'e'} on the {vIghro'} ?

To give the "as for the.." meaning ?
To mark the topic of the sentence ?
To give emphasis to the {vIghro'} word ?

Or all of the above ?
