Definition: "Preposition(al)" is a term used in English to describe an action or idea that starts with one or more words, as opposed to one or more clauses (which often end with punctuation marks like commas) or a number of other prepositions. For example: 1. Preposition("for") means "to prepare". 2. Preposition("of") means "from". 3. Preposition("by") means "by". In everyday English, you might hear this phrase used: "I bought some fresh bread for breakfast", which is a preposition phrase that describes a noun (the bread) as the action that started the sentence. The word "preposition(al)" is one of many ways to show how words are connected and interact with each other. It's a handy way to keep your writing clear, concise, and easy to read.
