Useful phrases – swearing

We all did it at school, huddled round dictionaries in the playground or

before interminable French or German lessons started, looking up naughty

words like ‘willy’ or ‘fanny’. Well, now CMC saves you the effort of

searching for swearwords, profanities, scatological phrases and words that

your gran would frown upon by gathering together a selection for your

delectation. And don’t tell me you’re not curious…

Note: If you are of a sensitive disposition, please do not read on. And

certainly don’t email me telling me that Welsh is a ‘pure’ language or the

language of heaven and therefore should not be sullied by such profanities.

If you can show me a Welsh speaking adult who doesn’t fuck in Welsh, then

I’ll show you someone who needs to get out more.

Source: All these phrases were collected from members of the CMC email list

or visitors to CMC so may reflect local dialects. If you have any swearwords

that you would like to add to this collection, please do email them to us.
