Changing Words to the Genitive Case

To change the words "ветвь," "гвоздь," and "вещь" to the genitive case in Russian, the following transformations can be made:

1. Ветвь (branch) becomes ветви in the genitive case. 2. Гвоздь (nail) becomes гвоздя in the genitive case. 3. Вещь (thing) becomes вещи in the genitive case.

These changes are made to reflect the grammatical case required by the context or sentence structure.
