Cwtch (pronounced like your are going to say cook, but replace the k with tch. It is a welsh word, essentially meaning "to make small". Not as in shrinking, but in various instances like: A covering or shelter, the small space under the staircase, a hug or cuddle (because you are making the space between you small), and it also means when you like someone because you have a small space in your heart for them.

So the connotations are typically of being closed around and conforting.

So you'd use it in these ways:

• your boots are over in the cwtch
• come here love and give your nan a lovely cwtch
• Bryn has a cwtch for Rhiannon
