The form listed in dictionaries is the bare infinitive, although the to-infinitive is often used in referring to verbs or in defining other verbs: "The word 'amble' means 'to walk slowly'"; "How do we conjugate the verb to go?" Source: Internet
The form without to is called the bare infinitive; the form introduced by to is called the full infinitive or to-infinitive. Source: Internet
The infinitive is the basic form of the verb (be, write, play), although there is also a "to-infinitive" (to be, to write, to play) used in many syntactical constructions. Source: Internet
