• Language

• Language Acquisition

Language Acquisition is the process by which humans acquire the capacity to perceive , produce and use words to understand and communicate.
The study of language is using two methods, that are The naturalistic approach and The experimental approach.
Phonological Development 

• Babbling
• Early phonetic process : Substitution, Syllable simplification
• Production versus perception
• Development order.

Morphological Development 

• A development sequence : Occurrence of the morpheme in utterance-final position-syllabicity-suspeceptibillity to stress-Obligatories-A straightforward relation between form and meaning-Lack of allomorphic variation-abscence of homophones-Clearly descernible semantic function.
• Morphemic rules
• Word formation rules

Developmental of Word Meaning

• Acquisition of Word Meaning :Overextension, The basis of overextension.
• Spatial and Dimensional Terms.

Syntactic Development 

•  The one word stage
• The two word stage
• The telegraphic stage
• Letter development

Determinants of Language Acquisition

• The Role of imitation and correction
• The role of parental speech
• The role of cognitive development
• The role of inborn knowledge

Grammatically development  

• A place for grammar
• Different Meaning for grammar
• Development of grammar
