STRUCTURE 

For positive sentences, use ‘will have’ after the pronoun, plus the verb in the past participle form. We often contract the form with an apostrophe. 

  • will have walked > I‘ll have walked
  • You will have walked > You‘ll have walked
  • He will have walked > He‘ll have walked
  • She will have walked > She‘ll have walked
  • It will have walked > It‘ll have walked
  • We will have walked > We‘ll have walked
  • They will have walked > They‘ll have walked 

For negative sentences, add ‘not’ after ‘will’.  We usually contract the form with an apostrophe.

  • I will not have walked > I won’t have walked
  • You will not have walked > You won’t have walked
  • He will not have walked > He won’t have walked
  • She will not have walked > She won’t have walked
  • It will not have walked > It won’t have walked
  • We will not have walked > We won’t have walked
  • They will not have walked > They won’t have walked
