We use still when we talk about a situation or condition that continues, it hasn’t stopped yet.
A: “Will there be a baseball game tonight?”
B: “I’m not sure. It’s still raining.” (It continues to rain)
Still often goes in front of have/has (usually the negative form has not/have not)
“I have lived in Japan for 5 years and I still haven’t been to a Kabuki performance.”
Still often has the feeling that a situation has continued longer than expected.
“I ordered my new computer 2 weeks ago and it still hasn’t arrived!”
