How is the phrase “from Armenia” formed differently in Eastern and Western Armenian?

The phrase "from Armenia" is formed using different ablative case endings in the two varieties of modern Armenian:

• Eastern Armenian: The phrase is rendered as Hayastan-ic‘, utilizing the -ic‘ suffix to indicate the ablative case.1
