Which characters does the theme of talkativeness relate to in Othello?

Talkativeness relates to several
characters.

1. Iago never
stops talking. I think we can classify him as a smooth talker too. He regularly talks to
the audience about his plans and he certainly talks to Roderigo, Cassio, and Othello to
shape what they are thinking and to cause them to act upon those
thoughts.

2. Emilia talks in a
manner to gossip just as all women do. She is a great representative of women for that
matter, but when she realized what had to be said, it was too
late:

I will
not charm my tongue; I am bound to speak.
My mistress here lies murdered in
her bed.

She said this when
it was time to tell the truth to Othello about Cassio and Desdemona, the truth being
that there was no affair.

3.
Bianca and Cassio speak with lovers language, yet their
relationship is
shallow:

CASSIO:

What make you from home?
How is it
with you, my most fair Bianca?(180)
I'faith, sweet love, I was coming to your
house.

BIANCA:And
I was going to your lodging, Cassio
What, keep a week away? seven days and
nights?
Eight score eight hours? and lovers' absent hours,
More
tedious than the dial eight score times?(185)
O weary reckoning!

4. Desdemona tries
to explain things to Othello both before she dies and when Cassio wants to speak with
Othello, but is too afraid. Unfortunately, Iago has already reached Othello's ear and
has given perceptions that would cause Othello not to believe his
wife.

This tale certainly demonstrates that whoever can
talk first and with the most persuasive power will be believed. The truth was
insignificant until it was revealed in the end and everyone was dying
anyway.
