Chinese grammar: type of word that is not a part of syntax analysis I remember my teacher giving an official name for words that are not a part of syntax analysis or not being considered in syntax analysis. 

For example:
如果把义放在后而把利摆在前 "If you put justice last and put profit first" 

In a syntax analysis what would you call 如果?
如果 is a conjunction meaning "in the event of", the same as if in English.
