Noun: "There is enough food for everyone." ("enough food" means a sufficient amount of food.)
Conclusion
The infinitive and gerund are two formal structures used in English to express purpose or reason. The adjective in this material is followed by the infinitive. The phrases 'in order to' and 'too' are also followed by an infinitive. Meanwhile, 'for' is part of a preposition, so it always precedes a gerund. The last one is 'enough,' which can be followed by either an infinitive or a gerund
