"Dw i'n hoffi Y Drenewydd."
Translation:I like Newtown.
Some Welsh towns have the definite article in their name which isn't translated into English. 'Y Drenewydd' is an important town in mid Wales which is known in English simply as 'Newtown'.
If this is phrase is not in capitals eg 'y drenewydd' then it would be referring to any 'new town'.
The 'new town' movement was an attempt in the 50s and later to establish artificial brand new towns in the UK in areas that were under developed economically. Some were very successful others were less so.
The only other one in Wales is in the south of the country which is know in both Welsh and English by its Welsh name Cwmbrân = (translation -'Valley of the Crows')
