With adjective and noun
When ‘enough’ is used with an adjective and a noun, two positions are possible but the meaning changes. Look at these two sentences.
We haven’t got big enough nails. None of the nails are as big as we need.
We haven’t got enough big nails. We have some big nails but we need more.
When enough comes between the adjective and the noun (big enough nails) it qualifies the adjective – it tells us that the nails aren’t big enough. When enough comes before the adjective it qualifies the noun phrase – it tells us that there aren’t enough nails.
