My English grammar would need a vigorous brush up, but I think I may be getting more help if I ask you guys.
I have the following doubts about English. If you feel to reply to even one of them, it would be helpful.
1. Nouns allowing to use the 's
I was always told that the 's can be used with people, but not with things. However, what about nouns that can identify a person or an abstract entity, like manufacturer?
If the manufacturer is a person, manufacturer's product would be acceptable. But if the manufacturer is a company, then it would not?
2. Feature, characteristic and trait
Are they interchangeable? If I were to translate 'me gustan las caracteristicas de estos autos' which would be more appropriate? In Spanish, it would refer both to the technical specifications as well as any details, like the car body, the internal finishings, etc.
Would it change in case of 'el motor es la principal carácteristica de los autos de esta marca'? In this case, it would be a distinctive trait of the brand.
3. make, manufacturer, producer
It is my understanding that 'make' is used for car make, only.
But then, what about manufacturer and producer? If it were any other good but a car, they would both be okay. But how do I pick the correct choice? Is manufacturer used for industrial manufacturing, only, while producer is for smaller batches, maybe a store or a craftsman?
4. brand and make
Again with make... In a sentence like 'el motor es la principal carácteristica de los autos de esta marca' can I still use make or should I switch to brand? I want to be consistent with terminology, so I'd rather stay with the same word if I were given the choice.
5. The bloody subjunctive
The subjunctive seems to be 'the beast' in any language, and English makes no exception.
I learned it this way: if + subj [clause].... then + would [action]
If I were a millionaire, I would buy a Ferrari. [from my English handbook some 15 years ago... I still remember it]
so... if I were to buy a computer again, it wouldn't be an Apple. / If I were young again, I would do things differently. / If I ever were to buy a Ferrari, I wouldn't buy it in red.
But I hear a lot of people (especially from the US), saying if I was young again...' / If I was to pick one, I'd pick the blue one
Is this a BrE vs AmE thing? In school we learned BrE and AmE was not accepted (!).
That's all for now, thank you!
