Bare infinitive

The bare infinitive is the form of the verb without "to".

The bare infinitive is used:

• as the main verb after the auxiliary verb do, or most modal auxiliary verbs (will, can, etc.): "I will go" (I will to go);
• after had better: "You had better ask him";
• with the verb help: "She helped him finish it";
• with why: "Why do it later?".
