Saturn is ___________ to be seen on a clear night with the naked eye.

Correct answer: bright enough

Explanation: 'Enough' follows adjectives and adverbs when it means 'sufficiently'. In this sentence, place 'enough' after the adjective 'bright' and before the infinitive phrase 'to be seen'.

• Rule: Put 'enough' after the adjective: adjective + enough

• Correct sentence example: Saturn is bright enough to be seen on a clear night with the naked eye.

• Why the other forms are wrong:

• 'enough bright' — wrong word order; 'enough' must follow the adjective.

• 'as enough bright' and 'bright as enough' — incorrect mixes of 'as...as' and 'enough'. Use 'as bright as' for comparisons or 'bright enough' to mean sufficient.
