Grammatical structure: Too kind a girl
Solution 1:
Yes, this structure is commonly found in English, but the article can only be the indefinite article.
(ref.) The indefinite article may also appear between an adjective and a noun when using the word too.
Here are, for instance, the most common nouns found when the adjective is "hard".
Here are those for "difficult".
It always means "sb/sth is a < noun > so < adj. > that it is not possible that < what follows > should not be true".
