Not vem depois de will, antes de have.

O particípio passado é a terceira forma das tabelas de verbos: written, gone, built. Ele nunca muda com o sujeito.

O padrão

Not fica entre will e have, contraindo-se em won’t have:

They will not have arrived. → They won’t have arrived.

Avisar que um prazo será perdido

É para isso que a negativa serve:

• The report won’t have been finished by Monday.
• The guests won’t have eaten, so keep something back.

Not yet, not until

Os dois caem naturalmente e afinam o prazo:

• She won’t have heard yet.
• The results won’t have been published until Friday.

A suposição negativa

Com by now, a negativa supõe que algo não aconteceu:

Don’t wait — they won’t have left yet.

De novo, nada aqui é futuro: é uma leitura do presente.
