Almost and nearly:

To refer to the progress of things, especially if we are measuring and counting things:

- You’re almost there.  - Estas quase la.

- It’s nearly 10 o’clock. - Sao quase 10 horas.

Extreme adjectives (impossible or frozen):

- That guy is almost impossible. – Aquele rapaz e quase impossivel

- The chicken is still nearly frozen. – A galinha esta praticamente congelada

We use almost (but not nearly) to soften statements:

- I almost wish I hadn’t offered to pay his fine. – Eu quase desejo nao me ter oferecido para pagar multa dele.

We use almost before any and before negative words such as no, none, never, nobody, nothing.

- You can find the history of almost any building. – Podes encontrar a historia de quase qualquer edificio

- She almost never raises her voice. – Ela quase nunca levanta a voz.

Not: She nearly never raises her voice.
