Forth vs. Fourth
Forth can is an adverb used to indicate someone or something is moving forward or coming out. For instance, a judge may ask the bailiff to bring forth the prisoner from wherever they're being held.
Fourth, on the other hand, is an ordinal number that is used as an adjective to indicate the number four in order. So if you have four people lined up in a row numbered one, two, three, and four in order; then the one person would be first, the two person second, the three person third, and finally, the four person would be fourth.
