Be not acknown on 't; I have use for it.
Go, leave me.
I will in Cassio's lodging lose this napkin,
And let him find it. Trifles light as air
Are to the jealous confirmations strong
As proofs of holy writ: this may do something.
The Moor already changes with my poison:
Dangerous conceits are, in their natures, poisons.
Which at the first are scarce found to distaste,
But with a little act upon the blood.
Burn like the mines of Sulphur. I did say so:
Look, where he comes!
Not poppy, nor mandragora,
Nor all the drowsy syrups of the world,
Shall ever medicine thee to that sweet sleep
Which thou owedst yesterday.
If I can fasten but one cup upon him, ["fasten" = metaphor for ensure he is caught]
With that which he hath drunk to-night already,
He'll be as full of quarrel and offence
As my young mistress' dog. Now, my sick fool Roderigo, [simile]
Whom love hath turn'd almost the wrong side out,
To Desdemona hath to-night caroused
Potations pottle-deep; and he's to watch:
Three lads of Cyprus, noble swelling spirits, [irony or sarcasm; Iago despises these men]
That hold their honours in a wary distance,
The very elements of this warlike isle, [does Iago have a clear purpose? how deeply can he plan?]
Have I to-night fluster'd with flowing cups, [cups = metonymy]
And they watch too. Now, 'mongst this flock of drunkards,
Am I to put our Cassio in some action
That may offend the isle.--But here they come:
If consequence do but approve my dream, [a personification]
My boat sails freely, both with wind and stream. [metaphor: his plans = a boat
