Question

Ok so we have to put accent and breve marks in the following sentence “Nor Mars his sword nor war’s quick fire shall burn”

Answer 1

Answer:

nor MARS his SWORD nor WAR'S quick FIRE shall BURN.

Explanation:

Accent marks or diacritical marks are those marks that are put either above or below a word to bring difference in the pronunciation, stress, or even meaning.

A breve is a mark that is put on an unstressed word. Breve symbolises a short or unstressed vowel in a word.

The given sentence is written in an iambic pentameter style which means that that are five meters with an unstressed syllable followed by a stressed syllable.

So, to depict an accent mark I have written the word in capital and breve in small letters.

nor MARS his SWORD nor WAR's quick FIRE shall BURN.

Answer 2

That sentence is in iambic pentameter. So accented words are bold:
Nor Mars his sword nor war's quick fire shall burn
