Or a noun in place of a noun,

or a verb in place of a verb,

or a plural in place of a singular or the reverse

or the style of absence in place of the style of address.

And sometimes to advance what deserves to be delayed

(in terms of language custom and grammar) or the reverse.

And sometimes due to the proliferation of pronouns

(and their reference to multiple sources) or the plurality of intended meanings for the single word.

And sometimes due to repetition and prolixity.

And sometimes for the sake of conciseness and brevity.

And the rational figurative speech.

So it behooves the fortunate brothers to become acquainted with the reality of these matters

and some of its examples at the beginning of the discussion,

and suffice themselves with symbols and indications in the places of detail.
