Stages of development for negation

The following stages of development for negation in English and German have been found among learners from different language backgrounds and different learning contexts (Ellis, R 1994: 99-101):

Stage 1 External negation
The negator - no, not in English, nein in German - is placed outside the statement:
no bicycle, no do it
nein helfen, nein spielen Katze.

Stage 2 Internal preverbal negation
The negator is placed 'inside', after the subject but before the main verb:
I no like it. It no bicycle
ich das nicht mach. Ich keine lerne Karate

At this point, learners of English and German have to face some grammatical complexity. In English, the negator not is placed after an auxiliary verb do and in front of the lexical verb: I do not (don't) like cats. Learners of English initially simplify the problem of the auxiliary by treating don't as an alternative to no and not, producing utterances such as He don't like it, I don't can do it.

Learners of German have to work out the distinction between the negator nicht, for verbal negation, and kein for negation of noun phrases. At the internal preverbal stage, nein ceases to be used so frequently, but learners simplify their new task by using nicht and kein randomly at first.

Stage 3 Postverbal negation
Gradually, English learners work out that the negator not has to be placed after the inflected verb, be it do or another auxiliary. Similarly, German learners develop post-verbal negation using nicht, and are gradually able to distinguish kein from nicht:
I can't play that one, She didn't believe me
Ich gehe nicht ins Kino, Ich habe keine Schwester

External and preverbal negation occur consistently in the early interlanguage, as well as in early child language, suggesting that they may be inherently 'easier' to acquire than postverbal negation (see Cook, 1993: 43). However, the learner's L1 may still have some influence. Those who have preverbal negation in their first language (eg Spanish and Italian speakers) are likely to take longer to move on to postverbal negation. It is as if their L1 knowledge is reinforcing a natural stategy. (For extended discussion, see Braidi, 1999: 25-28; Cook, 1993: 36-43 and Ellis, R, 1994: 99-101).
