The last few weeks' efforts have been much simpler than this week's & as a consequence I am in need of some assistance.
21A - Abhorrent to avoid the centre a lot (6)
I have ?A?F?L. The only thing that fits appears to be LAWFUL, but can't parse it.
The following all are intermingled :
53A - Native Greenlander perhaps accepting unconnected tips on basketball (7)
I???I?T (INBUILT?)
56A - Material beginning to solidify in spirits diluted with water (9)
G???G?A?N (GROSGRAIN?)
&
50D - As well for a bishop to go in and out (5)
T????
Any assistance welcomed.
I wouldn't swear to the accuracy of all the letters above cited.
