They're inclined to provide the right electric current (5)
I believe the answer is:
ramps
'they're inclined to provide' is the definition.
The definition suggests an adverb but the answer is not.
'right electric current' is the wordplay.
'right' becomes 'r' (common abbreviation).
'electric current' becomes 'amps' (I've seen this before. I am not sure about the 'electric' bit.).
'r'+'amps'='RAMPS'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for ramps that I've seen before include "Sloping passages" , "Slopings passages" , "Small road ridges for prams" , "Gradients" , "Slopes to calm traffic" .)
