You notice in the chart that we have three separate and distinct words in the Greek for immersion, sprinkling and pouring; and these words have their primary or proper, secondary or tropical meanings, all of which must be differentiated. The primary or proper meaning has reference to specific acts, the secondary meaning refers to things done by means of these specific acts, while the tropical or metaphorical meaning departs from the specific meaning of the words and therefore cannot have reference to the specific outward acts indicated by the words. For this reason it is a law of language, recognized by all scholars, that you must give a word its primary or proper meaning when it is employed in commanding an outward act, unless the context demands another meaning. Notice the English words _shoot_, _hang_ and _poison_. These express specific outward acts; and, then, in their secondary meaning, they mean to kill, but always to kill in the way indicated by the primary meaning of the word. A man can be hung, shot or poisoned without being killed; but if it is reported that he was hung, shot or poisoned, we would all understand that he was killed. However, you cannot conceive of words so changing their meaning, that when it is said a man was hung, it means that he was shot, or when it is said he was poisoned, it means he was hung. No more is it conceivable that when the Greek word _baptizoo_ (to immerse) was used, it meant to cleanse by sprinkling (_rantizoo_), or when the word _rantizoo_ (to sprinkle) was used, it meant to cleanse by immersing (_baptizoo_). These words refer primarily to separate and distinct outward acts. It is true they may meet in their secondary meaning in the idea _to cleanse_; but they always refer to cleansing in the way indicated by the primary meaning of the word used. When they travel so far from their primary or proper meaning, which has reference to specific outward acts, that their meaning is said to be tropical or metaphorical, they lose their specific idea and have no longer any reference to the specific acts denoted by the words. It is true that words can and do often change or enlarge their meaning. But this is always to supply a need created by the lack of a proper word to express an associated idea. Now, both the specific and general ideas with reference to the application of water are so copiously supplied with words in the Greek, that they preclude the necessity of changing the meaning of a word like _baptizoo_ to supply such a need. We have _louoo_, to wash or bathe the body; _niptoo_, to wash a part of the body, as the hands, feet, face, etc.; _plunoo_, to wash clothes; _brechoo_, to wet, to rain; _katharizoo_, to cleanse; _ekcheoo_, to pour; _rantizoo_, to sprinkle; _baptizoo_, to immerse, etc.
