Looking well ahead, relative finally settling in without a partner (4-5)
I believe the answer is:
long-range
'looking well ahead' is the definition.
I can't judge whether this defines the answer.
'relative finally settling in without a partner' is the wordplay.
'relative' becomes 'gran' (I've seen this before).
'finally' suggests the final letters.
'in' is an insertion indicator.
'without a partner' becomes 'lone' (I've seen this in another clue).
The final letter of 'settling' is 'g'.
'gran'+'g'='grang'
'grang' placed into 'lone' is 'LONG-RANGE'.
Can you help me to learn more?
(Other definitions for long-range that I've seen before include "Acting over a distance" , "Able to function at a great distance" , "Involving a long period of time stretching into the future" , "Effective over great distances" , "Covering great distance, or looking further ahead" .)
