I rather like the phrase "amenable to suggestion"
You can attach it to things easily:
My political views, amenable to suggestion, ...
But I'm afraid it may be redundant. According to this definition:
(of a person) open and responsive to suggestion; easily persuaded or controlled.
(of a thing) capable of being acted upon in a particular way; susceptible to.
I think it should be fine because "amenable" only involves suggestion when describing people. But according to this definition:
open or susceptible to suggestion; likely to listen, cooperate, etc.
it does involve suggestion.
In a formal context is "amenable to suggestion" too redundant? Is it redundant at all?
Thanks in advance!
