The above passage should further be compared with the survey of Caddington (1222): Dicunt juratores quod manerium istud defendit se versus regem pro x.
Est michi collatum Ihc istud nomen amatum," is not an unusual inscription on mediaeval black-letter bells, if I may use the expression.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "istud" in a variety of sentences. We hope that you will now be able to make sentences using this word.
