Questions & Answers about Wǒ hái bú tài xíguàn zhème zǎo qǐchuáng.

What does 还 mean here? Does it mean still?

Yes. In this sentence, 还 means still.

So 我还不太习惯这么早起床 means something like:

• I am still not quite used to getting up this early
• I still haven't really gotten used to getting up so early

It shows that the situation has not changed yet. The speaker expects that maybe later they will get used to it.

Compare:

• 我不太习惯这么早起床。 = I'm not very used to getting up this early.
• 我还不太习惯这么早起床。 = I'm still not very used to getting up this early.

So 还 adds the idea of up to now.

Why is it 不太习惯 instead of just 不习惯?

不太习惯 is softer and more natural in many everyday situations.

• 不习惯 = not used to
• 不太习惯 = not very used to / not quite used to

The word 太 often helps make the statement sound less absolute. In English, we do this too:

• I'm not used to it
• I'm not really used to it yet

So:

• 我不习惯这么早起床。 = stronger, more direct
• 我不太习惯这么早起床。 = softer, more conversational

With 还, the whole thing becomes very natural:

• 我还不太习惯这么早起床。
