All terms, whether technical or not, are only useful to those who
already know what they mean. So if you want to learn new concepts, then
you have to learn new terms. All terms are more or less arbitrarily
chosen. I don't see why it should be substantially harder to learn
arbitrarily chosen greek terms then to learn arbitrarily chosen english
terms.

I strongly disagree for three reasons. First, "function" as we use it in
programming is clearly a technical term, which has to be learned by
beginners. Second, "function" in Haskell means something else as
"function" in, e.g., Java. Third, function is in fact a highly ambiguous
technical term, meaning something else in almost every area. In my work,
I use at least the following meanings of "function":
* a special kind of relation
* the purpose or utility of a component in a system
* a subroutine in a computer program
* the role of a person in an organization
* the fact that something is working
* a symbol in a signature
* one feature of a system which offers several
I think "function" is actually an excellent example of an obscure
technical term which is hard to understand, which origins from
mathematics, which has to be mastered in order to understand Haskell,
and which often causes problems for beginners. Therefore, I'm confused
why you argue *against* such terms in general, but *for* the term
"function".
I tend to feel confronted by terms which I happen not yet to understand,
while taking the terms I already understand for granted. However, I try
to remind myself not to be stunned by mere words, but instead learn
about the concepts and their names which are new to me, and teach others
some of the concepts and their names which I already know. There is just
no point in complaining that one doesn't understand something, and so
much more in learning and teaching.
