2. ABSTRACT
Machine Translation is one of the major area under NLP. While translating English - Tamil, preposition in English sentences should be translated into postpositions in Tamil to make meaningful sentences.
This project mainly focused to eliminate the prepositional phrase attachment and orthographical errors.

3. MOTIVATION
Machine translation quality has improved substantially in recent years.
Prepositions are plays sound role in meaningful translation for any languages.
The prepositional phase errors are the major issue.
The motivation of this project is to improve the English-Tamil translation quality.
Use some semantic rule to correct the prepositional errors.

22. CONCLUSION
There has been a significant advancement in the area of machine translation than the existing system.
This work is mainly focused to identify the exact meaning of the preposition with respect to the content and place for English-Tamil translation.
Thus the accuracy of the proposed translation system is 92%, 97% and 94%.
