Often times "(s)" is added to the end of a word to represent one or more of something:
"He saved the file(s)."
What do you do when the plural of the word is not created by simply adding an "s?" Take the word "directory" for example:
"He copied the directory(s)."
That's clearly wrong...
"He copied the director(ies)."
...also clearly wrong.
What do I do with a word like this?
