omagh

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

'irish town' is the definition.
(town in County Tyrone)

'oh about to talk' is the wordplay.
'about' means one lot of letters goes inside another.
'to talk' becomes 'mag' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'oh' placed around 'mag' is 'OMAGH'.

'in' is the link.

Can you help me to learn more?
