fragile is an indispensable option in beamer presentations. However I never understood nor was able to find much information about how it got its name, which seems quite peculiar.

    Not all slides are fragile. I've to use it with listings or verbatim contents. It means that the content is not robust enough and need to be protected. – Ignasi Apr 18 '16 at 10:51
  • From the beameruserguide: "You must also use the [fragile] option for frames that include any “fragile” text, which is any text that is not “interpreted the way text is usually interpreted by TEX.” For example, if you use a package that (locally) redefined the meaning of, say, the character &, you must use this option." – user36296 Apr 18 '16 at 11:00
  • @StevenB.Segletes I see. I thought it's a Beamer specific thing. – xji Apr 18 '16 at 12:48
