reach

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

'attain' is the definition.
(I know that attain can be written as reach)

I don't understand the rest of the clue.

(Other definitions for reach that I've seen before include "Arrive at the destination" , "Attain - make contact with" , "Attain - continuous extent of water" , "Succeed in getting to" , "Arrive at; extend to" .)

I've seen this clue in The Irish Independent.
