The word 'convenience' occurs five times in the Shakespearean corpus with an unremkarkable distribution. The variant form 'conveniency' appears only in The Merchant of Venice and Othello and has some unusual context restrictions. In both scenes it collocates in the same line with 'all' and is spoken by an impatient man, who makes a plea to get on with things. Antonio speaks about Shylock to the court; Roderigo speaks to Iago:
Therefore I do beseech you
81
Make no moe offers, use no further means,
82 But with all brief and plain
conveniency
83
Let me have judgment and the Jew his will.
(Mev.
4.1.80-83)
175 Every day
thou daff'st me with some device,
176 Iago, and rather, as it seems to
me now, keep'st from
177 me all conveniency than suppliest
me with the least
178 advantage of hope. I will indeed
no longer endure it;
(Oth. 4.2.175-178
The resemblances, while not overwhelming, fit into the pattern of Iago/Shylock echoes that
many scholars have noted.
