Make ends meet? (6)
'make ends meet?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for splice that I've seen before include "Weave (strands of rope) together" , "Join the ends by weaving the strands together" , "Knit" , "Join (ropes) by interweaving strands" , "Unite (strands of rope)" .)
(Another definition for getby that I've seen is " manage satisfactorily".)
