Remember these placement rules depending on what "enough" modifies:
Before nouns: enough + noun → We have enough time.
After adjectives/adverbs: adjective/adverb + enough → quick enough, skilled enough.
Use with result: ... enough to + verb → enough data to decide.
If it modifies a noun, put 'enough' before the noun; if it modifies quality (adjective/adverb), put it after the word.
