(s) VS (ies)

[Minis]

Hi,

I'm having a difficulty to decide whether to use (s) or (ies) when combining singular and plural forms in one word, for the word ending in "y".

E.g. faculty(s) or faculty(ies) ?

I saw both variations are used. I'm not sure which one is correct.

Thank you in advance!

To make plurals with nouns ending in y:

If a noun ends in y: add s

There is a TV play on tonight.
There are three TV plays on tonight.

Exception

If a noun ends in consonant + y: change y to ies

There is one baby in the room.
There are three babies in the room.

See: spelling rules - adding -s

Thank you for your reply Josef.
I guess I didn't explain my question correctly. It's not about spelling rules for the plurals ending with y, but specifically about the form of writing the 's' ending in parentheses. I'm writing a document for users of the software, and I need to say: "If you need to select facility(s)" - meaning that they can choose one or several. Now the question is, do I put 's' in parentheses or (ies).

Thank you

Mr Josef explained it correctly however you couldn't catch it.
Now your question is with faculty so mentioned above as well that the word faculty ends with Consonant + Y so it takes IES. it should be Faculties not facultys. With the second word Facility it should also be Facilities not facilits because it the word ends with Consonant + Y. Hope it is understood clearly now.
