adept, adapt and adopt

The single vowel is the only difference in these three similar words. I have used these and yet get confused with the usage, especially the last two. This post should clear this for good.

Adept is expertise at something. 

I am adept at blogging!

Bond is adept at spying.

Adapt is to get comfortable with changing times or situations. 

We continue to adapt to the fast technology changes all around us.

Being from the country side, I have to gradually adapt to the city life.

Adopt is to own or bring something into use. 

We adopt a child. 

We adopted a security policy that was effectively rolled out in the organization.

I had one situation where a new technology was being rolled out in my organization. Would this be adoption or adaptation (or adaption)? I finally figured out that we have adopted the technology that will be the de facto standard for users and now users have to go through the adaption programs to get hands-on with the change. 

Yes “adaption” and “adaptation” are different forms of the word adapt. I have read and used “adaptation” all along and now I know that "adaption" looks like an urban adoption of the original word!

The movie hunger games is an adaptation of a book with the same name.

We devised an adaption program to educate users and bring them onboard with new services.
