You are writing a sentence and suddenly pause: should you use fourth or forth? It is a small spelling and grammar question, but it can easily cause confusion. Both words are real English words, both sound similar, and both appear often in everyday writing.
The important difference is that fourth and forth do not mean the same thing.
Fourth is an ordinal number. It means number four in a sequence. For example, if four people are standing in a line, the last person is the fourth person.
Forth usually means forward, onward, or toward a place or position. You may see it in expressions such as go forth, and so forth, and back and forth.
This difference matters at school, at work, in emails, on social media, and in everyday conversations. A missing u can completely change the meaning of your sentence.
