①Do these two sentences make sense to you? ②If so, could you explain to me the connotations of these two sentences?③Which sentence better fits in the context?

1--I haven't been speaking English for for long.
2--I haven't spoken English for so long.

(Context: I was busy with university work and didn't have time practicing English. After a long time, I finally have the time to pick up my English and practice my speaking skill)

@Hyyyyyyy

I haven’t spoken English in quite awhile.

Your first sentence – assuming that the mistakes in it were not intended – tells us that you literally just began learning. The second sentence is fine for your purpose, but I do try to tell adults to avoid using the word – so – as an intensifier in this way.

I haven’t spoken English for sooooooo long! – It looks funny and it sounds funny once or twice, but this is really the way that teenagers speak and it’s not a great habit to get into if you are not a teenager and have no intention of becoming one soon.

Quite awhile
Quite some time

This is the proper way to do it 👍
