Onto vs. Into: Qual é a diferença?

In casual conversation, people often use `in` for movement (e.g., 'Put it in the box'). However, in writing and formal speech, `into` is much better because it clearly shows movement.

Both are used, but `log into` is becoming the standard compound preposition for accessing websites or computers. If you use `log in` as the verb, then `to` follows it separately.

Use `onto` for movement to a surface. Use `on to` when 'on' is part of the verb (like 'hold on' or 'move on').

Not always! It can also mean a change of state (e.g., 'water turns into ice') or a strong interest (e.g., 'I am into jazz').

Yes, it is a fully accepted preposition in modern English, though it was once considered informal or incorrect by some grammarians.

`Unto` is archaic and mostly found in the Bible or old literature (e.g., 'Do unto others'). You don't need to use it in modern English.

Yes, it can describe moving further into a period of time, like 'late into the night'.

This is a common English quirk. We use `onto` or `on` for public transport where you can stand up and walk (bus, train, plane) and `into` or `in` for smaller vehicles where you must sit (car, taxi).
