These set phrases are also often used with specific verbs. The placement of prepositional phrases are often placed at the end of sentences. Here are some examples: He learned the play by heart.The company had to sell the property at a loss.We decided to move to New York for better or worse. Other prepositional phrases can also be placed at the beginning of sentences. From my point of view, I'd say we need to change our provider.By the way, Tom told me he would come over this afternoon.From now on, let's try to talk once a week on the phone. Prepositional phrases often have opposite forms such as at most/least, at a profit/loss, for better/worse, under obligation/no obligation, etc. It's important to learn to identify prepositional phrases, as they are used to connect ideas and modify verbs.
