Hey there, I was noticing while doing both apps simultaneously that WaniKani lists 締結する as “to ratify” while KaniWani defines it as “to conclude, enter, or execute.” I figured KaniWani just took everything directly from WaniKani, so it was just a bit confusing. Thanks for reading!
The meaning was changed in WaniKani a few months ago. KaniWani is run by an individual user, so I don’t know how they manage importing those changes when they happen.
