Please be patient

Our volunteers look into many questions every day; sometimes it takes them a little while to answer.

Pro tip: you can rename the thread title with `.tr <thread name>`

Make it descriptive, including relevant context, but also to the point. This way you improve your chances of getting a more relevant and specific answer.

If there's a ne it should be only

But the ne can be skipped especially in speaking

But not every verb can use a "that"

But like if it's "that" it introduces sth else so it should be clear

When it's only it's an adverb

[sullen night]

I mean, in English, if you just said 'that', how can I tell if you mean the conjunction or the determiner?

If I only see 'I know that', the sentence can either be 'I know that you are wrong (that = conjunction)' or 'I know that car (that = determiner modifying 'car')'

Context determines meaning, always

In the sentences « Je vois que tu as réparé ta voiture  » and « Je vois que ta voiture », it's clear which is which because the former has another clause after it – which means it's a conjunction meaning 'that' – and the latter is followed only by an object – which means it's the restriction adverb meaning 'only'.

I will say in english the conjunction typically has a reduced vowel while the demonstrative typically doesn't, but the actually grammatical context is also important as you say

[sullen night]

That is also true but again you used context which is in this case the sound of the conjunction versus the determiner
