Answer 2

Answer:

They advised the king to regulate his diet. ‘To regulate’ is the infinitive.

Explanation:

An infinitive is a grammatical term. It usually uses the word ‘to’. The verbs with ‘to’, like- to go, to eat, to sleep are called infinitives as they do not have a specific tense and those without ‘to’ are known as bare infinitives.  

‘They advised the king to regulate his diet.’ Here in this sentence ‘to regulate’ denotes the infinitive verb that has been used. The two simple sentences have been combined and made into one simple sentence using ‘to’.
