That's an indication that the text is too wide for the frame for some reason. Common causes are the application of No Break to a large block of text (many new users mistake No Break for turning off hyphenation), long strings of text where the words are separated by non-breaking spaces and hyphenation is turned off, Keep options that require all of the text to remain together in a frame that is too small to hold it, or indents, either at the frame level or the paragraph level, that make the column too narrow to hold text.
You can open the story in Story Editor view (Edit > Edit in Story Editor or Cmd/Ctrl + Y) so that you can see the text. The easiest way to figure ot the problem is then to select the first line of overset text -- there will be a red line indicator in story editor -- and look at all of those formatting possibilities.
THANK YOU SO MUCH !
OK, explain to me why I cannot paste this text?
here is file:
I want to paste the text:
Immíttet Angelus Dómini in circúitu timéntium eum, et erípiet eos: gustáte et vidéte, quóniam suávis est Dóminus.
into the slot starting "in te speravi"
I go to paste it, using "Paste without formatting" and In Design CS 5.5 will not allow it. Why?

You have applied No Break to the existing text in the frame you want to paste your new text in. When you paste without formatting, you apply also No Break to the whole text of this frame. Just select it and uncheck the No Break attribute.
jmlevy is correct.
You may find it easier to select the text in the story editor, but you can slect the frame, then open the character panel, then the panel flyout menu and click No Break twice.
