I learnt that there is a clear difference in meaning amomg "next, coming and following" , but I also learnt that people in speaking tend to ignore the rules and to use them interchangeably.
Here is the rule I took in:
Next:
usually used as a synonym of "following" for a singular-noun time period, :
Let's see next month (= if now it is March, we are seeing sometime in April)
Let's see next Friday (= whatever day it is today, on Friday of next week)
"In 3 months' time I'm going to Italy.
The next(=the following) month I'm going to Germany."
Although the context anyway steers you in the right direction, it should be incorrect to form sentences like:
"In 3 months' time I'm going to Italy. The next months I'm staying there to work as a bankclerk."
And:
"In 3 months time I'm going to Italy. Next month I'm going to Germany."
It is clear that in the first sentence we mean "following" and in the second one we mean "coming", but as a rule these are an incorrect usages of "next"
(in the first sentence we are using "next" for a plural time unit, while in the second sentence we are using "next" as a synonym of "coming" whereas it is as a rule always a synonym of "following", and so if we were strict grammarians we should consider the meaning of that "next"="following", and so we should consider that I'm going to Germany in 4 months' time
) and so we should avoid them (please give me a confirmation of that).
The only exception to the rule is the fixed expression "the next few months", in which we have a plural time unit and "next" accompanied by "few" exceptionally means "coming" and not "following".
Coming:
Often strenghtened by "this" which is put before "coming", must be interpreted as relative to the present. It can be used both for singular and plural time units :
"We're meeting (this/the) coming Friday", means the Friday of this week
"In 3 months time I'm going to Italy. The
coming month I'm going to Germany." , means I am going to Germany in 1 month's time.
"In 3 months time I'm going to Italy. The
coming two months I'm going to Germany." , means I am going to Germany in 2 months' time.
"Coming" never acts as synonym of "following". For instance in the sentence:
"We started a big project at this time last year. The next(=following) months were difficult."
In this sentence "next", "following" and "coming"
can't be used interchangeably. "next"="following" can be used interchangeably to mean the months after the beginning of the project. "coming"="the next few" can be used interchangeably to mean the future months with respect to the present.
"We started a big project at this time last year. The coming(=the next few) months are difficult."
Following:
"following" is only used if you have already established a time period in the past or the future (not the present) and you are talking about something that happens relative to that time period:
I had a very relaxing holiday, but I would study hard the following month.
I had a very relaxing holiday, but I would study hard the following months.
meaning the months after the holiday.
Finally, is it correct to say:
I will study hard in the months following the classwork. ??
