meaning - "Still" and "Yet" as Conjunctions

I know there are already many posts on still and yet, but I really find it difficult to use them as conjunction as in following sentences:

1. It's a small car, yet/still it's surprisingly spacious


2. He has a good job, and yet/still he never seems to have any money


3. The weather was cold and wet. yet/still, we had a great time.

So my question is when should I use yet and when should I use still, when using it as a conjunction, and what is the correct option for sentences above?

Answer

Yet is a conjunction meaning nevertheless or however. While still may appear in conjunctive phrases like but still, it is not itself a conjunction. Therefore:

It's a small car, yet it's surprisingly spacious.

The weather was cold and wet, yet we had a great time.

You can use either word in conjunctive phrases. Yet usually carries a sense of negation, so and yet means the same thing as but still.

He has a good job, and yet he never seems to have any money.

He has a good job, but still he never seems to have any money.
