Final answer:
Iago is described as 'honest' by the other characters in the play Othello, which is ironic given his deceptive nature.
Step-by-step explanation:
In Othello, the main characters consistently describe Iago using the adjective 'honest'. Despite Iago's duplicitous nature, his outward demeanor and manipulative actions lead the characters to regard him as trustworthy and sincere throughout most of the play. This profound irony underscores Iago's role as a master deceiver and stands in stark contrast to his true, malicious intentions.
