In the following passage, which words are emphasized? How and why are the words emphasized?Father, and wife, and gentlemen, adieu. I will to...

There is also the emphasis required by the rhythm of
iambic pentameter (stressed syllables emphasized in
bold):

readability="18">

Fath-er, and
wife, and gentle-men,
a-dieu

I
will to Ve-nice;
Sun-day comes
a-pace.

We will
have rings, and
things, and fine
a-rray

And
kiss me, Kate, we
will be married
o'Sun-day.

Except
for the first line, which has a feminine ending (on an unstressed syllable), all lines
have their necessary stressed and unstressed syllables -- five
each.

Understanding the iambic rhythm really points out,
for example, the stress on the word "will" as mentioned in other responses to this
question.  You also notice that Shakespeare almost always stresses the action or verb
("will", "married", etc). in a line and never the pronoun ("I," "We,"
"me").
