There are certain words that express the great essentials of human thought, as objects, qualities, or actions; these are nouns, adjectives, and verbs. Such words must always make up the substance of language. Yet these are dependent for their full value and utility upon another class of words, the thought-connectives, that simply indicate relation; these are prepositions, conjunctions, relative pronouns and adverbs. If we compare words of the former class to the bricks that make up the substance of a wall, we may compare those of the latter class the thought-connectives to the mortar that binds the separate elements into the cohesion and unity of a single structure.
