| Usage notes | Use 'presumably' when you think something is true but don't have definite proof. It’s more formal than using 'probably' and is often used in writing or serious conversations. | Use 'probably' when you want to indicate that something is likely true or will happen. It's appropriate in both spoken and written English, but avoid in very formal contexts where more certain language is expected. |
