I really hate this "synonyms" category. At least say what they're synonyms for. I entered "curve" and "bend" but was still incorrect.

nicely twisty and weavy!

Nice.

I very quickly identified what turned out to be the right connections, but kept falling for your red herrings and managed to solve only one group before my time ran out. Damn you and your fiendish traps!

After that it was plain sailing.

Thanks for the fun grid!

I don’t think “curve” and “bend” are really synonyms here. The other verbs describe multiple bends and curves as in the way a river behaves on flat land.

I should have included “wind” in the acceptable answers.

Thanks for the comments

turns???

I think turn is like curve and bend. You’ll have to judge for yourself whether to award yourself the point. I think it’s very close but not quite a synonym.
