 +**Motivation**: During translation from an SVO based language (English) to an SOV based language (Korean) we might need to change the word order from SVO to SOV.

 +**Task**: Change the word order from SVO to SOV.

 +**Instructions**:

 +  * To find an object to a verb, look for objects among effective children of a verb (''$child->get_attr('afun') eq 'Obj' ''). That implies working on analytical layer. 
 +  * Once you have node ''$object'' and node ''$verb'', use method TODO  
 +  * For debugging, a method returning word order of a node is useful: ''$node->get_attr('ord')''. It can be used to print out nodes sorted by attribute ''ord''.

-In dependency approach a question "where to hang prepositions" arises. In praguian style (PDT), prepositions are heads of the subtree and the noun/pronoun is dependent on the preposition. However, another ordering might be preferable: The noun/pronoun might be the head of subtree, while the preposition would take the role of a modifier.+**Motivation**: In dependency approach a question "where to hang prepositions" arises.
