So BIAS is my other answer. BIS - repeat but not sure how the A fits in. Something unsatisfying about this puzzle and I rather regret the time I've spent on it.
all 9 are angrammatically linked connected to the second word of the idol 4 in one way 5 in another.
The words in the preamble help sort out unchecked in the 9 words/phrases
Please can anyone help me with the highlighting - I've looked at anagrams of star and synonyms and vice versa but can't link any of that to 2 adjacent clues? 8a scratch was the nearest I got!
