Hello,

How are you?

I have two questions regarding the following structures with "prefer". Which of them is ungrammatical (if any)? Are there any differences in their meanings and usages?

1- I prefer swimming to walking.

2- I prefer to swim rather than walk.

3- I would prefer swimming to walking.

4- I would prefer to swim rather than walk.

I greatly appreciate your help in advance.

They are all grammatical. They all mean the same thing. Those with "would" are slightly gentler, weaker statements than those without "would".

"Hello,

1- I prefer swimming to walking. (OK.)

2- I prefer to swim rather than [to] walk. (OK.)

3- I would prefer swimming to walking. (I'd say : I would rather swim than walk, or simply I'd prefer to swim.)

4- I would prefer to swim rather than walk. (The same, I'd say : I would rather swim than walk, or simply I'd prefer to swim.)
