[quote=“Nelsie, post:67, topic:21579, full:true”]By any reasonable English grammar, if the H in “historian” is weakened or non-existent, then you say “an” before it. Which I do. Sometimes.

Non-existent, yes. Weakened, whatever that is, no. I am still convinced -nh- goes against English phonology, and it appears -anh- and -anx- regularly became -ah- and -ax- in common Germanic phonology, thus thought [which loses the n before x] contrasts with think [which retains the n before k].
