If you savour something, you enjoy it a lot, usually by taking your time and paying close attention to it.
Savouring something is a good feeling, like when you eat your favorite candy very slowly and enjoy every bit of it.
Examples:
She savoured every bite of the delicious cake.
I savoured the beautiful sunset.
He savoured the victory for a long time.
I savoured the ice cream so much that it melted!
She savoured the book so much that she read it three times.
He savoured the moment and smiled.
