-al in hierarchies
[edit]Welcome to Wikipedia! In the literature, it is very common to see "arithemtical hierarchy", "analytical hierarchy", and "hyperarithmetical hierarchy" - e.g. in Soare's book or Rogers' book. I don't think there is any strong reason based on the literature to remove the -al, as long as an existing article is consistent about its usage. And the titles of our articles all seem to have the "-al" in them. The talk page of the article can be used to explain if there is a strong reason for the change. — Carl (CBM · talk) 20:20, 24 May 2018 (UTC)
