According to the terminology of linguistic typology, Basque is a SOV (subject-object-verb) language, and Spanish or English are, on the other hand, SVO type.
There is a general tendency that most languages should change into SVO order from SOV order and that's why pronominal objects change their position in Chinese.
本文认为,汉语代词宾语前置变后置顺应了世界语言从SOV语序向SVO语序发展的总体趋势。
In SOV and SVO sentence patterns, the members of sentence are the same, but the construction of word order is not, displaying different structural features and sequence of words.
