:: i meant that since Indo-European ablaut is about ablaut in IE langs then it should be expected that that article will link to a more general article (i.e. ablaut/apophony). 

 :: i think that since the term ablaut is used to refer to ablaut in any language family having an article about ablaut that describes only IE langs is not acceptable. you are suggesting a redefinition of the term (i.e. having it refer only to IE langs). 

 :: i have never looked at a grammar of Hebrew, so i cant comment on this. even if you have read a particular grammar of a non-IE lang that uses the term apophony and not the term ablaut, this does not mean that the term ablaut cannot not have been used in that grammar (this is an just editorial preference). i have seen the term ablaut used with respect to Athabascan langs, Yokutsan langs, Otomanguean langs, Cushitic langs, Semitic langs, Utian langs, Siouan langs, & Kartvelian langs. –
