As the Chicago Manual of Style recommends, we follow the recommendations in Merriam-Webster's Collegiate Dictionary.  The latest lexical research is available in the online edition.  When there are multiple options presented, Chicago recommends going with the first option. Nimble's policy is to do so unless there are compelling reasons to prefer another spelling because of considerations such as unique characteristics of the knowledge domain.
