How can a weapons plant make fertilizers?

All I know about some complex patterns of the part of speech combination is this: An adj + noun + noun/ Article + noun(or adj) + noun.

But it doesn't look that the above sentences apply the rules I know.

Q) how can s be added to a noun weapon in those structures.

How can a weapons plant make fertilizers?
There seems to be something missing here. I don't find anything about fertilizers.
Terrorists often use chemical fertilizers (phosphates, I think) to make bombs, so you could say that a terrorist weapons plant used fertilizer as an ingredient in their production.

We often add "s" to a noun when we want to use it as an adjective.

I know from experience which nouns add it and which ones don't, but I'm afraid I can't give you a rule for it.

A milk plant.

An automobile plant.

A weapon(s) factory/plant.

A suit factory.

A cosmetic(s) factory.

A pharmaceutical(s) factory.

I can't think of a case using the "s" in which it's not really optional.

Can you give me a sentence which conforms to this pattern? It makes my head spin. Emotion: rofl

This is not a sentence. Can you recheck your source?

a huge weapons plant

"Plant" is the only noun here.

Perhaps some people would consider "weapons plant" a compound noun.

He was carrying a big baseball bat. (same structure - without the "s")

Very perceptive. Normally when a noun is used as a modifier, it is in the singular. weapons is an exception. (sports is another exception, by the way.) I wish there were a list of the exceptions. There can't be very many of them. Unfortunately, I don't know of any such list.

Hi, Jim,

Do you consider the "s" optional on "weapons" and "sports"?

Seems like I've seen "sport drink" as well as "sports drink," but I'm not 100% sure.

Well, it all boils down to usage, really. I can't say I've ever seen weapon factory or sport drink, so in my idiolect those are oddities, and the regular forms are weapons factory and sports drink. There's also people mover, a "horizontal escalator" seen in airports.

I consider mathematics, politics, and the like, singulars, so I have no problem saying that mathematics textbook is regular. I haven't yet considered how I really feel about cosmetics and pharmaceuticals. Emotion: smile

Of course I had to look. Emotion: embarrassed

"Sports drink" and "weapons factory" are both four-to-one over the singular versions, akdg to Google.

Thank you very much CJ, AV for the answers plus a series of conferences.

Avange. I cut some out in the example sentence No.2 because I thought they are adjuncts; you see the No.2 is not a sentence because of that.. sorry, my guess was turned out to be wrong!

2.

An adj + noun + noun/ Article + noun(or adj) + noun.

These rules make your head spin? hhhhh that's really fun.

I think the examples can be : a huge tire factory, a thirty minute walk etc.

Thank you
Got it! Thanks! I thought it was all one sentence. Emotion: thinking
