This study aims to argue for two purposes. One is to find a type which a root is precede element of ‘x하-’. The other is assert that ‘하-’ is a word and ‘x하-’ is a compound word. In other words, we try to reveal that ‘하-’ can be integrated into the ‘verb root’, such as shown in ‘비롯하-’. Through this, we claim that ‘하-’ is classified as the ‘word’. The first reason is to reconsider the double way that the one morpheme is classified differently as the suffix or the word. Another reason is that it is hard to classify ‘시키-, 드리-’ which are replaced ‘하-’ as the suffix. In this article, for this, we used the synchronic way and diachronic way together. We can explain briefly a grammar of ‘하-’ in ‘x하-’ and ‘x를 하-’ by this assertion.
