Bound to be descriptive of apprentices (8)

I believe the answer is:

articled

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

'bound' is the definition.
(I know that bound can be written as articled)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for articled that I've seen before include "Like apprentices, perhaps" , "Bound as an apprentice (eg, in a legal office)" , "- Clerk, trainee solicitor" , "Like some clerks" .)

I've seen this clue in The Irish Independent.
