In a row with TUC, union so put out (10)

Ross

I believe the answer is:

continuous

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

'in a row' is the definition.
I can't tell whether this defines the answer.

'tuc union so put out' is the wordplay.
'put out' indicates an anagram.
'tuc'+'union'+'so'='tucunionso'
'tucunionso' with letters rearranged gives 'CONTINUOUS'.

'with' acts as a link.

Can you help me to learn more?

(Other definitions for continuous that I've seen before include "Without interruption" , "Uninterrupted" , "without stopping" .)
