If is called also a conjunction. His is not true it is always a verb, being only a contracted form of give. The fact is the same with though; it is a verb, but defective. To the syntax, I have added several new rules and illustrations; the British Grammars, in this particular, being very defective. In deed, so defective and erroneous are the British Grammars, and the compilations in the United States, formed on their principles, that without some further helps, the construction of many established and legitimate phrases and sentences in our language, cannot be explained.
