I’d appreciate it if someone would answer my question concerning the following 2 sentences. Thanks in advance.
A: Customs vary depending on the country.
B: Customs vary depending on countries.
I think A is right, and B isn’t. The reason is, in order to see the difference of customs at large, customs of each specific country must be cited, so a definite article is used. Is my explanation right?
There is nothing wrong with the original sentences. As you indicate, the singular is the usual form:
Customs vary depending on the country.
The plural would not be used in most circumstances, but it is not incorrect to do so.
I dislike Anglophile’s first suggestion and feel if you wish to use that type of phrase it should be:
Customs vary by country.
‘Customs depend on the country concerned’ is more long-winded, and as there are more succinct options available, this rambling version is unnecessary.
Thanks a lot again. I appreciate and try to emulate the way you always talk and explain things. Well, I may say one is better than the other, which, I believe, is not so sinful. In fact we see many expressions like ‘vary with’, ‘vary from’, ‘vary between’, ‘vary according to’ and so on. I think all the following ‘combinations’ are acceptable.
Customs in my country vary with those in yours. As they vary between our countries, we may say they vary from country to country. Customs may vary by country, so we cannot say they cannot vary according to the country. Let customs vary depending on the country. What if they vary in their observance!
— Thank you, anqlophile, James and beeesneees.
I understand there are many variations for my example. As a matter of fact, my job is to teach English to my students in my country, and I wish to give them only a few high-frequency examples. So I’d like you to choose often-used examples among the following sentences.
— Thank you anqlophile and beeeseneees. I’d like you to choose often-used [often heard] ones. So your accepted ones are often-used ones, not grammatically-OK ones, aren’t they?
I am also a basic learner and the first thing came into my mind after reading the question was the same as yours. Vary+according is more often than vary+depend as i have observed yet.
