Hey… I am struggling with the reading of 一山 . I dont understand why kun yomi is used instead of the on yomi. ひとやま and not いちさん or some kind of that. And yeah I am aware that this vocab not teached in WaniKani but perhaps someone can enlighten me with the reason.
I thought there were this rule that you have to use on yomi when there are two kanjis next to each other.
