interjection

The word 'interjection' originates from Latin interiectiōn-, the stem of interiectiō, which is derived from the verb intericere meaning 'to throw between'. This verb itself is a compound of the prefix inter- ('between') and jacere ('to throw'). The literal sense of 'throwing something in between' evolved into the grammatical and rhetorical meaning of inserting an exclamation or remark into a conversation or discourse. In English, it was adopted in the late 14th century, first for the rhetorical act of interruption, and later solidified in the 16th century for the part of speech that expresses a sudden emotion inserted into speech.
