Except that's wrong English[1]. At least that's not correct usage according to what I learned in school. A colon follows an independent clause: something that could in essence be a complete sentence and expresses a complete thought. The colon separates that independent clause from examples or an explanation or clarification of that independent clause. The phrase "Our three weapons are" isn't an independent clause. It has the transitive verb "are" but no predicate nominative. You've placed the colon in the middle of an independent clause between the verb "are" and the predicate nominative phrase "fear, surprise, and ruthless efficiency, and an almost fanatical devotion to the Pope". Your example should be something like this [accurace of the quotation aside]: The Spanish Inquisition has three main weapons: fear, surprise, ruthless efficiency, and an almost fanatical devotion to the Pope! > Although the bullet list is indented, the header line "Our three weapons > are" looks like something is missing, Something is missing.

Yup. [1] Since all posts criticising grammar or spelling will have an above average number of grammar and spelling errors, I thought I'd get a head start on it. -- Grant Edwards grant.b.edwards Yow!
