I thought 'giants being only human, but this perhaps' was to say the least a convoluted definition and had not previously come across 'trip' as a way. Also, I am struggling to understand buddy at #7, given the e and m in the shorter word in the southernmost World are checked by the reversals and once account is taken of its longer word there is only one option to complete each of the unclued entries (although the result means having to simply reverse a word in the clue, which is rather unsatisfactory to the extent I would be happy to confess to flawed reasoning !)
