Infinitive

When the word to is followed by a verb, it is an infinitive; for example, to walk , to look , to talk . Thus, to walk is the infinitive form of the verb walk . The word to is not used as a preposition. Infinitive makes use of the base form of a verb to follow to , without a change in its form to express a function such as a tense, mood, person, number, case and gender. Without to , the verb form is called the bare infinitive, and sometimes, the form that follows to is called the to-infinitive or the full infinitive (to + simple form/base form of the verb).

Its

Its is different from it’s . When an apostrophe is not used with the word its , it indicates possession or determiner. When an apostrophe is used, it’s is a contraction of it is . Its is used to indicate it is or it has . Inserting an apostrophe so that it becomes it's when you mean possession makes the sentence wrong grammatically. Without apostrophe Without an apostrophe, the word its indicates belonging to a noun that has already been mentioned.

Without apostrophe

Examples:

  • My dog is always licking its paw.

    (The use of its indicates the paw belongs to the dog.)

  • It flapped its wings and flew away.
  • Their house has its own swimming pool.
