Hey
generis AjiteshArunI don't have any issue with options.
I want to ask about the usage of
for reducing in this sentence.
We cannot refute on this but most of the times I have seen experts stress on the usage of
to reduce.
Can you help me get what exactly is the difference between the two and how can we ascertain when to use which one ?
Hi
penco,
My reply is not specific to this question (maybe you're also thinking about
this other question?), but the
for + gerund call may come down to whether we're looking at the purpose of a
specific person or entity (or maybe a
specific situation):
I. Purpose of a person: Don't use
for + gerund.
1.
I went to the market to buy vegetables. (
source) ←
To + plain form is appropriate here (for the purpose of a specific person/situation).
2.
I went to the market for buying vegetables. ←
For + gerund is incorrect (for the purpose of a specific person/situation).
3.
I went to the market for vegetables. ←
For + noun is fine, but slightly ambiguous: is this a "market for vegetables"? This is not a major problem, as
to can be ambiguous as well, and sentences like "I went somewhere (X) for some Y" are very common.
II. General purpose of a noun: Both
for + gerund and the
to + plain form can be used to introduce the
general purpose of something (a
noun):
4.
... the Food and Drug Administration (FDA) approved the first drug for treating COVID-19. (
source)
5.
... a drug to treat kidney stones, for instance, was raised from $1.50 per pill to $30. (
source)
This is especially common with the verb
(be) used (
a drug used for treating X and
a drug used to treat X are both correct).
III. A specific situation: Try not to use
for + gerund.
6.
An experimental cocktail of drugs was used to treat the president. ← This is what we'd normally expect to hear.
7.
An experimental cocktail of drugs was used for treating the president. ← This is a very specific ("one-time") situation, and I would not use
for + gerund here.
Just keep in mind, though, that with certain words,
to + plain form is much more common (or in other cases, much less common) than
for + gerund, leading to preference calls.
TL;DR: Choosing between [
to + plain form] and [
for + gerund] isn't always easy. Try to prioritise other entry points.
