Therefore the main meaning of a word is given by replacing the letters in a word by the letter types, the detailed meaning of the word is gotten by considering the second levels of the letters. The tool and environmental words are assumed to be the same sequence of letters. It is assumed that the tool letters always win so that the environmental word is defeated on every letter from last to first. Long vowel sounds indicate no breakdown or minor breakdown during interaction, short vowels indicate breakdown occurs. For consonants it is assumed breakdown generally occurs since less energy is involved for consonants.
Higher levels can transmit lower level action.
Lower levels cannot transmit higher level actions. This is important in determining possible interactions of words. A tool is a device of size that can be handled by a person. It operates on a similar size structure in the environment. The tool may destroy one of these parts completely by breaking it down by repeated interaction into lower and lower levels until it is completely de-aggregated or vaporized.
