What is parameter setting"
In trying to explain the universality and rapidity of 
language acquisition, the notion of parameter setting offers 
one explanation to why we know how to generate grammatically 
correct language in numerous different cases without having 
had to memorise them or even heard them before. Parameters 
corresponds to certain general features of languages and 
have a wide effect on the grammatical climate. A classical 
example is the pro-drop or null subject parameter that 
determines whether it is correct to drop the subject in a 
sentence:
Example:
English: I love you  (subject-verb-object)
Spanish: Te Quiero (object-(conjugated)verb)
(you love)
In Spanish, the verb is conjugated so that you know who 
loves just by looking at the ending (the -o in present) , 
and this makes it perfectly sensible to omit the subject. So 
the null-subject parameter is set to on in Spanish, and 
off in English ( It would not be grammatically correct to 
say love you or you love) Because grammatical rules in a 
language interact so tightly, the null-subject parameter 
implies a subset of other grammatical features or rules:
Example:
English:  Who do you think phoned? 
Spanish:  Quien piensas QUE llamaba?
(Who (do you) think THAT phoned?)  
Adding "that" to the sentence is incorrect in English 
because the null-subject parameter does not allow dropping 
the subject, whereas it makes the sentence correct in 
Spanish. (I am not going to explain why, but this subset 
rule interacts with the null-subject parameter.)
There are also other parameters like the word order 
parameter that corresponds to how free the word-order is 
allowed to be: E.g.in German the verb usually comes last, 
the Scandinavian languages have a less strict word order 
than English, and in the Aborigine language Warlpiri, word 
order within a clause is almost totally free (meaning there 
are no or few rules for the order of subject, verbs and 
objects). 
The most important part of the parameter setting theory is 
to understand how the very nature of our language 
acquisition offers a lot of  short-cuts. When learning 
languages, we dont need to know every grammatical rule 
because we assume that a language takes a certain subset 
of grammatical rules once we have the parameters sorted out: 
When I learned Spanish, it seemed natural to me to add the 
that to the sentence in the example (above) , even though it 
is ungrammatical in my own language (which is not a 
pro-drop language). 
Thinking about the vast number of possible combinations of 
words and tenses, it seems impossible to acquire language by 
memorising input alone. The parameter setting theory lends 
an explanation to this.
