When to use inverted word-order like "great an option"? [closed]

Solution 1:

My hunch is that OP misheard.

The inverted "great an option" form is used most frequently in specific constructs, such as "so [adjective] a [noun]" and "as [adjective] a [noun]". (Both of these, for what it's worth, are comparative constructs.)

Ex: That's not so great an option.

Ex #2: I'd rather not live in as large a house as this.

Ex #3: So great a surgeon is she that she could do this operation blindfolded.

Edit: Another context in which this occurs is in constructions of emphasis, such as: How lovely a film that was!

Solution 2:

The only way I can make sense of the phrase

That is great an option!

is if I put in a comma

That is great, an option!

which means "Here is an option, it's great to have it".
