Modal or modal verb
Modal verbs are also auxiliary verbs. They are placed in front of all other auxiliary verbs.

 

Examples:

  • He will be sentenced for murder.
  • You should have come earlier.

 

Non-finite clause
A non-finite clause is a subordinate clause that uses a participle or an infinitive. Non-finite clauses do not have tenses, and they do not show the time at which something happened.
 
Object complement
Some transitive verbs are followed by an object and its complement. This complement is called the object complement. It describes the object.

 

Examples:

  • We think you have unfairly labeled him selfish.
  • The new evidence proved him guilty.
  • The employer found him negligent in not reporting the theft.
