text: Local councils and the National Assembly for Wales use Welsh as a quasi-official language , issuing their literature and publicity in Welsh versions ( e.g. letters to parents from schools , library information , and council information ) and most road signs in Wales are in English and Welsh , including the Welsh placenames .
simplified: Many people in Wales say they can understand some form of Welsh , such as spoken , written , or can read Welsh , even if they do not speak it all the time . Almost all Welsh people understand and can use the English language .
