What lovers sometimes did in underdeveloped countries (6)

I believe the answer is:

eloped

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

'what lovers sometimes did' is the definition.
I can't tell whether this definition defines the answer.

'in underdeveloped countries' is the wordplay.
'in' indicates a hidden word.
'ELOPED' is hidden in the letters of 'underdeveloped countries'.

Can you help me to learn more?

(Other definitions for eloped that I've seen before include "Ran away to marry" , "Went off" , "Ran away to get married" .)

I've seen this clue in the Evening Standard.
