Following the example of 'take' -> 'taker, 'create' -> 'creater' and so on, we might expect that there would exist a noun '*raper' from the verb 'rape'. Instead we have the noun 'rapist'. Is there a term for such non-words that are formed according to the derivation rules of a language but don't exist?
1In fact, 'raper' exists; but I wanted to ask if your question refers specifically to derived non-words like this, if you're including compounds (such as German is famous for, like 'carboat'), or if you're including phonologically-legal non-words ('flample').– Jeremy NeedleJan 5, 2014 at 19:32
What do you mean by your 'flample' example? I'm referring to non-words that are the result of applying natural word-creation rules to existing words. So '*goed' (as a past participle of 'go'), '*travellist' (to mean 'traveller') and similar.– dbmag9Jan 5, 2014 at 19:36
4Your example of *goed is inflectional rather than derivational, by the way. Generating a regular inflection when an irregular inflection is expected is sometimes called overregularization. Another related term is blocking--the derivation *unequality (unequal + -ity) can be said to be blocked by the existence of inequality.– user2081Jan 5, 2014 at 23:58

To expand on snailboat's comment above, you might want to consult Laurie Bauer’s ‘English Word Formation’ (Cambridge UP 1983) for some background here. Quote (p. 87):
Blocking is the name given by Aronoff (1976: 43) to the phenomenon of the non-occurrence of a complex form because of the existence of another form. The form which causes the blocking may itself be complex or simplex. For example, Bolinger (1975: 109) points out that, despite the productivity of –er suffixation in English, there is no word ‘stealer’ because of the prior existence of the word ‘thief’ which carries the appropriate meaning; the existence of forms like ‘bad’ and ‘small’ blocks the formation of *ungood and *unbig; the prior existence of ‘enlist’ prevents the use of ‘list’ as a verb with that meaning (Clark and Clark, 1979: 798).
In fact, ‘stealer’ or ‘raper’ would be termed by Bauer ‘nonce formations’: ‘new complex words coined by a speaker/writer on the spur of the moment to cover some immediate need.’ (p. 45) Blocking takes place when these fail to lexicalize. As Bauer details, linguists have suggested that there are some suffixes whose formations are never blocked, for instance –ness. This leads them to posit ‘an inverse relationship between productivity and lexicalization’. It also implies that productivity is a cline phenomenon. Interesting stuff!
(Aronoff 1976 is ‘Word Formation in Generative Grammar’, by the way.)
I would say the closest you can get is "infantile speech", not because it actually is infantile speech but because I think people would understand what type of words the one you are referring to is.
The words you are referring to, like *goed, are obtained by overgeneralising rules, which is usually what children do and what adults try to correct. Actually, the *goed was one of the examples in a seminar child speech development I goed to ;)
