For those who don’t engage in rote memorization, a distinction is made between assimilable as where liquids mix and assimilatable in dealing with cultural adaptations. Check issues of Comparative Culture Review, a scholarly publication where the term “assimilatable” appears with some frequency.

For the benefit of us rote memorizing people from India, please enlighten us as to how far did you go up your rectum to pull out that word?
