Translation of barmherzig

This is not so easy, my dear! Unless you have learned Latin, then Italian is not an easy language... I'm new here, I found the site through Google. How does it exactly work here? I want to sign up.
I've also looked at the interface, and found it a good idea to include the colloquial option. Would it be very complicated to add the most important regional check box, like Spain, South America or Central America?
The weather is never really good this time of the year here. I have found a new girlfriend and guess what: she is Spanish. Yesterday we went out for the 4th time. Tomorrow I will see her again.
