That which we call a rose by any other name would smell as sweet.


It’s only your name that is my enemy;
You are yourself, not even a Montague.
What’s “Montague?” It is not a hand, or a foot, or an arm, or a face, or any other part belonging to a man.
O, be some other name!

What’s in a name? That which we call a rose would smell as sweet if it had any other name.

Romeo, throw your name away;
And for that name, which isn’t part of you, take all of me.

Shakespeare’s Romeo and Juliet (II, ii, 1-2), 1594
