I'm a little stuck... Click here to teach me more about this clue!

This might be a double definition.

'pattern' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.

'the ulster doctor?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.

'for' is the link.

Can you help me to learn more?
