At first I thought short-form adjectives were quite easy after seeing how they are formed. But when to use them turned out to be more complex. Here I have 5 sentences that made me confuse since they are all similar in terms of structure:
Александр очень ленив.
Маша очень общительная.
Моя бабушка очень добрая.
Он очень глуп.
Итальянки очень красивы.
How do I decide which form to use when?
