What is the English name of the Welsh city known as "Abertawe"?

I've just started to learn Welsh on Duo Lingo and luckily, this is one answer I knew without using any of my life lines! 😊

I've lived in Wales/Cymru (Rhondda C.T) for nearly 12 years,learned many Welsh words and loved the people very much. Diolch yn fawr for the question and for bringing memories back.
