GG! Tricky links, but interesting. Keep it up!

Needs an s on the end of pet.

Unorthodox grid. Easy enough due to only having one overlap across the entire grid, but not very enjoyable to be honest.

Nice concept but a far too easy as it's nearly impossible to fit in any crossovers with these groups.

I man am regal, a German am i. Full marks for trying for interesting...

Missing s on one of the clues

Got it despite the missing s but put " make new words when reversed " which wasn't accepted for the backwards group. :-(

You've probably sussed it The missing S in the purple group.
Think it would of been better if red group had some crossover red herrings. Otherwise fine.

Being picky- in the homophones group I don't think "err" is pronounced the same as "air".

I like the concept. I like grids based on good spots and lateral thinking over obscure knowledge. I agree with the other comments about a few wobbles but do please keep trying these!

enjoyable. I would like to point out (and idk if you set it up as a valid answer), but an 'emordnilap' (backwards of palindrome) is defined as a pair of phrases or words that are spelled as mirrors of each other (desserts and stressed, for example) so you should accept that answer
