this is how words are constructed from route form:
eg. to show tense (verbs) or comparison (adjectives)

Eg jump + ed - to create the past tense
+ ing - to create present continuous
Eg big + (g) er - to create comparative
+ (g) est - to create superiative.

Stage 1 - around 18 months: during the 2 word stage, children start to use rising intonation to indicate a question. 'Go walk'.
Stage 2 - 2 - 3: in telegraphic talk, children continue to use rising intonation but also use wh - words, eg where tractor or what mummy doing? They use a wider range of interrogative pronouns. Such as why, when and how?
Stage 3 - 3 upwards: children use subject-verb inversion eg can I see it? They also start to use auxiliary verbs for the first time. Eg what is mummy doing

Stage 1 - around 18 months: children will use no or not to make things negative, normally at the beginning of a phrase rather than at the end. 'No bed.
Stage 2 - between 2 and 3: children start to use no and not in front of verbs too, such as 'I know want juice'. They develop the use of contracted negatives such as cant and don't.
Stage 3 - 3 years upwards: children stop using no and not the same way they did in stage 1. They use cant and don't correctly and start using other negative contractions such as didn't and wont, but isn't develops later.

Front constatnts- (b,d,p,t) come before back constants (g and k) this is because need muscle control from back of mouth
plosives-(b,d,g,k,p,t) com before fricatives (f,sh, v,z) because they need teeth to make these sounds and they don't develop these till there older.
plosives at the beginning of a word (book) comes before those at the end (book) and don't emphasise last letter of a word which is imitation theory.
fricatives at the end of a word (lousie) come before those at the beginning (spike) because when the fricative is in the middle of the word the 's' is much softer, however if it is the first letter there is more empathises.
constant clusters reduced to one constant  (gramma=jamma). this is known as constant clusters reduction or CCR as it is easier to articulate one of these sounds.
constant clusters at the end of a word (orange) come before those at the beginning (green) because it flows better but two separate sounds so can say them better.

Over Extension - When a child uses a single lexical item to name all things which share similar characteristics. Eg all four legged animals - dog.
Under Extension - When a child applies to narrow a meaning for a lexical item. Such as a child only recognising their teddy bear as  a 'bear'. They will not accept that other bears are also called bear.

Hypernyms, Synonyms and Antonyms
