questions to start with

The verb ought is a finite verb. Does this answer your question?



Should is more common, but they are both acceptable and both commonly used.



The first one is definitely correct.

The second one is false because good is an adjective, and an adjective is applied to set of 0 or more elements...but you need to specify the set of elements by using an article such as 'a'. Got it?

It's a little more complicated than that, though...because the following sentences are also correct:

ex: "I kicked him once again for good measure."

ex: "It is good practice to sell."



These terms are commonly used...in literature. Nobody talks this way in common speech.

Thanks stuh

Welll... one might say "at your soivice" (after the Noo Yawk accent in certain old comedies) or "at your dispose-all" (mimicking the name of a garbage disposal device) in jest...
