This picture shows part of my snippets in vim.

I believe it provides you hint about the source of the suggestion:

  • [A] the word is used in this buffer
  • [B] the word is used in another buffer
  • [F] the suggestion comes from the file system
  • [S] the suggestion comes from the snippets list
  • [LS] the suggestion is provided by the Language Server
  • ...

You can get the full list of sources using the following command:

:CocList sources

More information in the Coc documentation

For Language Server suggestions you get an additional information about the type of the suggestion:

  • M Module
  • S Snippet
  • f function
  • v value
  • m method
  • ...
