The 'plural' of software is "software" and not "softwares" unlike what many others think.
'Software' is a collective noun and is continuous, rather than discrete. It therefore doesn't take a plural. To make it simpler to understand, think of "software" like "water", "deer," or "sheep". Basically, it's pronounced and spelled the same whether in 'singular' form or 'plural' form.
When you say or use the term 'software', it could be singular or plural. It depends of the context. For example:
The company sells software (In this context, it could mean one program or it could also mean 20)
The company sells many different types of software. (In this context, this is definitely plural, although the word software is used.)
In short, remember this:
The 'plural' form for the term 'software' is 'software'.
Don't let anyone tell you any differently.
P.S. I am sorry if I make any grammar mistakes here. Admittedly, I am not really 'that good' in English. Thanks.
