Consentio tecum de sermone medioaevali Latino, Mattew, atque pro correctione linguae Anglicae quam non satis bene novi, gratias ago.

Matthew Rubush (X) Jan 6, 2015:

I think you mean "we ordered the letters to be sent". As for mitto v. expedio, the text appears to be medieval and so maybe expedio is okay--medieval Latin does its own thing, and is not the Latin of Cicero or Caesar. Lewis and Short gives for expedio "to fetch out, bring forward, procure, make ready, prepare." More context would be helpful, of course. On another note, I think the plural form iussimus may be taken as singular because it could be a "majestic plural".
