Briefly discuss the causes language change.

1) Sound assimilation: Sound assimilation refers to the physiological effect of one sound on an-other. In an assimilative process, successive sounds are made identical, or more similar, to one another in terms of place or manner of articulation, or of haplology, the loss of one of two phonetically similar syllables in sequence.
2) Rule simplification and regularization: Some changes are the result of simplification and regularization. The plural forms of borrowed words are usually irregular, thus complex.
3) Internal borrowing: In order to reduce the number of exceptional or irregular morphemes, speakers of a particular language may borrow a rule from one part of the grammar and apply it generally.
4) Elaboration: Rule elaboration occurs when there is a need to reduce ambiguity and increase communicative clarity or expressiveness. If a particular grammatical feature is lost as a result of a change in the phonological system, some other feature may be added in another component of the grammar.
5) Social triggers: Socio-political changes such as wars, invasions, occupation, colonization, and language planning and standardization policies lead to language changes.
6) Cultural transmission: Although a new generation has to find a way of using the language of the previous generation, it has to find expressions that can best communicate the views and concepts of the time and the changed and ever-changing social life, and recreate the language of the community.
7) Children's approximation toward the adult grammar: Children usually construct their personal grammars by themselves and generalize rules from the linguistic information they hear.
