| Just FYI, "A software" is grammatically incorrect, as Software is
| a mass noun, not a collective noun. "Softwares" isn't a word, for
| instance. (Similar to "money", in that you wouldn't say "I have a
| money, you have a money, and together we have two monies", you
| just say "I have money, you have money, together we have more
| money".)

| People saying 'codes' and 'softwares' is one of my pet peeves.

| I'm an American, btw. It's just 'code' and 'software' to me.
| Now I just use it as a hint that the person isn't American,
| much like when someone says 'maths'.

| Couldn't there be a collection of software? Hence softwares?

| Software can be considered to be already plural in a sense,
| because it refers to the set of programs/procedures needed to
| perform a specific task.

| Similar with money, you can have multiple _dollars_ , but you
| don't have multiple _monies_.
|
| "Hardware" also works this way, but it's probably more
| obvious to people. If I have some hardware, and I buy more
| hardware, I wouldn't say "I now have two hardwares."
