When you integrate quotations in this way, you do not use any special punctuation. Instead, you should punctuate the sentence just as you would if all of the words were your own. No punctuation is needed in the sentences above in part because the sentences do not follow the pattern explained under number 1 and 2 above: there is not a complete sentence in front of the quotations, and a word such as "says," "said," or "asks" does not appear directly in front of the quoted words.
Comma placement before a quotation also causes people trouble. Notice that in 'The bells on the Monk's bridle ring "in a whistlynge wynd als cleere…"' there is no comma after "ring" and before the beginning of the quote? This is because the quotation works grammatically in the sentence. In this case, the first letter of the quotation should be lower case (unless the first word is a proper noun). With shorter quotations you should attempt to do this wherever possible on stylistic grounds. Here are some examples of quotations integrated into the grammar of the sentence.
