Why maths, physics, economics but not

philosophies, laws, biologies?

Presuming you’re talking about STEM subjects? Biology is a science so would be included.

We will always need lawyers - I’m sure law is another subject that is encouraged.

Not sure what good philosophy would do now for society personally.

I missed out some words! I wondered why some subjects are pluralised but not others.

What are the missed words ?

The OP is asking why some subjects are plural - eg mathematics - whilst others are singular - eg law.

Americans have math

Inherited from ancient Greek. The plural ones are like ‘the something things’ the singular ones more like ‘the study of something’

Maybe because when you study mathematics you study a group of subjects, algebra, calculus, geometry etc

But law covers a range of stuff - commercial property etc ?

Bahaha i was thinking far too deeply!

My view would be that the different types of law are like the different branches of geometry (euclidean, non-euclidean, solid, plane etc), but those branches aren't related to number theory for example.

But conversely don't they say sports when we'd say sport.?

We have "field sports" and "team sports" plural all coming under the generic "sport" singular. I'm giving up now!

They’re not plural words, they just end in s. So physics isn’t the study of multiple physic and mathematics doesn’t mean many mathematic.

i know what I mean but I can necessarily explain it!

Ehtymology or linguistics?
