The new Welsh Language Commissioner, Meri Huws has set herself the task of moving Welsh into a new era. An era in which it is finally recognised in law as an official language of Wales.
It was long argued that there is no such thing as an official language in Britain, largely because English is so dominant that it hardly needs legal protection.
Now under a law passed by the Assembly last year, Welsh has official status and is to be treated no less favourably than English.
The Commissioner has what the Welsh Government calls 'strong enforcement powers' to protect the rights of Welsh speakers to access services in the language and she can launch an official investigation into any interference in people's freedom to speak Welsh to one another.
She will start with powers over many public services, not necessarily provided by government or local councils but by businesses licensed by them. So gas and electricity companies, telecom providers and bus and train operators could all be affected. Any organisation receiving at least £400,000 a year of taxpayers' money can be brought within her reach.
Meri Huws is a former chair of the Welsh Language Society, an organisation that has not been afraid to break the law in its 50 year fight to raise Welsh from a position when it had virtually no official status at all. Now the law will be on her side.
