strive to

@YBYeats the word "Strive" is an intransitive verb meaning "try hard to achieve something".
For the object/noun/pronoun the preposition that is always used is "for". So the above mentioned sentence is not correct.
The correct one:
We encourage all members to strive for the highest standards.

"Strive" when used as an infinitive will be dealt just as a nomal.

So "strive for something" or "strive to do something".

As fas as the verb "Aspire" is concerned, it has a slight different meaning.
Strive = Try hard to get.
Aspire = Having a desire (in heart) to get.
i.e. Aspire has nothing to do with "try" where as strive has a lot.
OR
The one who aspires to (do) something may not be trying to achieve it as it is a mere desire (no matter how strong it may be). While the one who strives is already TRYING HARD.

hope that answers.

No.

Strive for something (perfection? success?). Strive to do something.

Sorry to repeat myopic's advice. I didn't take the time to read it. My bad*.


* not good English btw!

Thank you, Mctag~

In dictionaries I find only GRATEFUL TO SOMEBODY FOR SOMETHING, but can I say this?

-I am grateful for somebody...

You cannot be grateful "for" anyone, instead, you can be thankful to someone for doing something good for you.

Hope that answers.

No, but the sentence is incomplete. You could add a bit to make it work.*

Being grateful is showing gratitude.
You have to show gratitude for something, and to somebody.


*examples on request.

examples:

I am grateful for somebody coming every day to change the cat litter. It's a job I don't like doing myself.

I am grateful for somebody, anybody, taking any notice of what I am saying.

Thank you~
