I was thinking about how little I use the word among and how I would phrase the dictionary's example sentences for it. Most of it involved substitution with the word with. Then I noticed something. For the sentence, "There are peanuts among the almonds," I say, "There are peanuts in with the almonds." However, Dictionary.com, the O.E.D., and Merriam-Webster only list "in with" as meaning "associating with" or "on friendly terms with."
How common is this use of "in with" to mean among; would this be understood by a majority of speakers on both sides of the pond; and would this be acceptable under the three Cs (context, convention, and circumstance)?
