Avail yourself of something
Incorrect : I availed the opportunity to improve my English.
Correct : I availed myself of the opportunity to improve my English.
Note: The verb “avail” means “to be of use” and it is usually used in questions and negatives. For example:
It avails nothing to cry.
This sentence means that it is no use crying. But the phrase "avail oneself of” means "to make good use of'. In the correct sentence above, it is used in this sense.
