The basic requirements for language acquisition:
1 - Exposure
It is the first basic requirement for language acquisition. If we take a child born of Moroccan parents and put him in another social environment, such as Italy, he will speak the language spoken there (i.e. Italian) not Moroccan Arabic. This is called cultural transmission, not genetic transmission. If the child were not exposed to a human language, “the language faculty” (that is the ability to acquire language) with which he is born, cannot be activated.
2 - Physical Fitness
There is no language output if language faculty was not activated. This leads us to say that language acquisition requires both the auditory and the acoustic input.
3 - The Critical Age
The critical age, called Puberty, occurs in the area where language is. Language acquisition has to be activated before this age. If the language faculty is not activated on time that is before this age language acquisition will certainly fail.

Stages of L 1st Acquisition:
1 - Pre- Linguistic Period:
  a.       Cooing
Children learn to recognize the distinctive sounds, the phonemes of the language they hear from birth long before they are able to pronounce them. Infants can distinguish between /p/ and /b/ at three or four months (in an experiment with /ba/ played vs. /pa/, a two month infant showed awareness of the change). But children do not learn how to use these sounds until much later-- around the second year or later--as shown by the experiment with /pok/ and /bok/.
            Between six and eight weeks the first cooing sounds are produced, generally when the baby is in a settled state. These sounds develop alongside crying, gradually becoming more frequent and more varied, as the child responds to the mother’s smiles and speech. They are quieter, lower pitched, and more musical than crying, usually consisting of a short, vowel-like sound preceded by a consonant-like sound made towards the back of the mouth many have nasal quality.

   b.     Vocal play:
During cooing stage there is a great deal of lip movement and tongue thrusting, which it is thought may be a form of imitation. This leads between twenty and thirty weeks, to vocal play. The sounds of vocal play are much steadier and longer than those of cooing. Most segments last over one second, and consist of consonant + vowel-like sequences that are frequently repeated. They are usually at a high pitch level, and involve wide glides from high to low. (Crystal)

    c.       Babbling stage:
Children around the sixth to the ninth month begin to differentiate between the sounds and select the sounds that exist in their environment. This stage is essential to proper language acquisition because it familiarizes children with the sounds of their voices, allowing them to gain control over their vocalizations, and it is characterized by indiscriminate utterance of speech sounds. This stage is essential to proper language acquisition because it familiarizes children with the sounds of their voices, allowing them to gain control over their vocalizations.
The fact that all children (including the congenitally deaf) go through a babbling stage, regardless of language and culture, and make very similar kinds of sounds at this time suggests that humans are biologically predisposed to go through this phase. (Akmajian, Demers, Farmer, & Harnish, 1997)
Babbling is a smaller set of sounds is used with greater frequency and stability, to produce the [bababa] and other sequences known as reduplicated babbling.  (Crystal, 2007)

Reduplicative babbling in child language acquisition

During the period 6 to 11 months after birth, all typically developing infants go through a stage of reduplicated or canonical babbling (Stark 198, Oller, 1980 as cited in Wikipedia). Canonical babbling is characterized by repetition of identical or nearly identical consonant-vowel combinations, such as 'nanana' or 'didididi'. It appears as a progression of language development as infants experiment with their vocal apparatus and home in on the sounds used in their native language. Canonical/reduplicated babbling also appears at a time when general rhythmic behavior, such as rhythmic hand movements and rhythmic kicking, appear. Canonical babbling is distinguished from earlier syllabic and vocal play, which has less structure.

During babbling stage, the brain seems to be controlling the development of babbling and early speech in a similar way, so that a set of well-practiced sounds is available for use at time when children become intellectually capable of using sound for the communication of meaning. (Crystal, 2007)

The linguistic period:
    a.       One word (holophrastic) stage.
At some point in the late part of the first year of life or the early part of the second year, the child begins using recognizable words of the native language. These words are usually the names of familiar people, animals, and objects in the child’s environment (mama, dada, kitty, doggie, ball, bottle, cup) and words indicating certain actions and demands (More, No). In this stage a certain child might use the word (doggie) to refer not just to dogs but to all common animals in the environment (overextension). In contrast, a child might use the word (doggie) to refer not to all dogs but only to certain specific dogs (underextension). (Akmajian, Demers, Farmer, & Harnish, 1997)
A particular sound often used in a child’s environment (such as in the name of a sibling or a pet) can cause that sound to be used much earlier than it otherwise might. Some children have favorite sounds, which they introduce into many words, whether the sound is in the adult version or not. Others avoid sounds for example, persistently dropping certain consonants at the ends of words. Several studies showed the way children change the sounds of the language when they attempt to use them:
They tend to replace fricative consonants by stops: see → [ti:]
They tend to replace velar consonants by alveolar ones: gone → [don]
They avoid consonant clusters: sky → [kaI]
They tend to omit consonants at the ends of words: hat → [ha]
They often drop unstressed syllables: banana → [nana]   (Crystal, 2007)

Overextension Vs underextension:
 
During one word stage another phenomenon usually occurs which is overextension or underextension. A certain child might use the word doggie to refer not just to dogs but to all common animals in the environment (overextension). In contrast, a child might use the word doggie to refer not to all dogs (all animals that could properly be referred to by the word doggie) but only to certain specific dogs (underextension). (Akmajian, Demers, Farmer, & Harnish, 1997)
Deaf babies whose parents use sign language begin making their first word/gestures around eight months. This stage is characterized by the production of actual speech signs. Often the words are simplified: "du" for duck, "ba" for bottle. When the child has acquired about 50 words he develops regular pronunciation patterns.
    b.      The Two-Word Utterances:
This stage is around 18-24 months; babies begin to use "mini-sentences" with simple semantic relations. They produce two- word utterances which can show different combination of word order. In this stage, the words lack morphological and syntactic markers but we can notice that there is a word order. And it is the beginning of real communication, and may resemble early proto-languages, such as give milk as a request for a drink and daddy home to observe that the father has returned.
During second year, as simple sentences develop, a wider range of attitudes is expressed, and prosody begins to signal differences in emphasis. At this point, it becomes possible to distinguish such general sentences as Daddy gone from the contrastive Daddy gone (not someone else).
Generally in this stage, children who are asked to repeat sentences may simply leave out the determiners, modals and verbal auxiliaries, verbal inflections, etc., and often pronouns as well. The same pattern can be seen in their own spontaneous utterances.

    c.       Telegraphic Stage:
Telegraphic stage or early multiword stage (better multi-morpheme), "Telegraphic" sentence structures of lexical rather than functional or grammatical morphemes appear. It nearly starts from the second year of babies’ birth. And they quickly progress to real grammar in short sentences, correctly placing words in proper order as in mommy call doggie - though this is not entirely correct, it shows an understanding of English sentence structure, the word forms are beginning to vary, inflectional morphemes begin to appear, and the use of simple prepositions become apparent. The child pronunciation is closer to the adult one.

Later development:
 
All children, no matter how rapid or how pedestrian their rate of acquisition, proceed systematically through the same learning stages for any particular linguistic structure.
 
How do children acquire WH questions?
 
The first wh words to be acquired are typically what and where, followed by who, how, and why; when, which, and whose are relatively late acquisitions. An early example of this is found in the work of Brown’s colleagues, Edward Klima and Ursula Bellugi, who proved that children learning English produce two different types of WH questions before they eventually come up with the correct adult version. They identified three distinct stages:
 
     a.      Use of WH word but no auxiliary verb employed.
What Daddy doing?
Why you laughing?
Where Mommy go?

    b.      Use of WH word and auxiliary verb after subject.
Where she will go?
Why doggy can’t see?
Why you don’t know?

     c.       Use of WH word and auxiliary verb before subject.
Where will she go?
Why can’t doggy see?
Why don’t you know?

How do children acquire yes/no question?
 
According to Brown’s early fieldwork there are 3 different stages of using yes/no questions:
    a.      Use of NO at the start of the sentence.
No the sun shining.
No Mary do it.
    b.      Use of NO inside the sentence but no auxiliary or BE verb.
There no rabbits.
I no taste it.
     c.       Use of NOT with appropriate abbreviation of auxiliary or BE.
Penny didn’t laugh.
It’s not raining. (Scovel, 2009)
