Rock the French after the Spanish one gets qualified (8)
I believe the answer is:
eligible
'qualified' is the definition.
(similar in meaning)
'rock the french after the spanish one' is the wordplay.
'rock' becomes 'gib' (both are nicknames for Gibraltar).
'the french' becomes 'le' ('the' in French).
'after' says to put letters next to each other.
'the spanish' becomes 'el' ('the' in Spanish).
'one' becomes 'i' (Roman numeral).
'gib'+'le'='gible'
'el'+'i'='eli'
'gible' after 'eli' is 'ELIGIBLE'.
'gets' is the link.
(Other definitions for eligible that I've seen before include "Regarded as desirable, say for marriage" , "Flashing lamp" , "Qualified, entitled" , "Satisfying the appropriate conditions" , "Suitable or deserving" .)
