Structure with Look Up
Understanding the grammatical structure of look up for each of its meanings is crucial for correct usage. This phrasal verb can be transitive (requiring an object) and sometimes separable (the object can come between "look" and "up"), or intransitive (not requiring an object) depending on the context. Let's break down its common meanings and their typical sentence structures.
Meaning 1: To search for information
This is arguably the most frequent use of look up. It means to find a piece of specific information by consulting a reference source like a dictionary, encyclopedia, phone book, or an online search engine. When used with this meaning, look up is transitive and separable.
Structure 1 (Separable - Noun Object): Subject + look + [object/information] + up
- Explanation: The noun object (the information being sought) can be placed between "look" and "up".
- Example 1: I need to look the train schedule up before we leave.
- Example 2: Could you look that unfamiliar word up for me?
Structure 2 (Separable - Pronoun Object): Subject + look + [pronoun object: it, them, etc.] + up
- Explanation: If the object is a pronoun (like it, them, this, that), it must go between "look" and "up".
- Example 1: The address? I'll look it up on the map.
- Example 2: If you don't understand these phrasal verbs, you should look them up.
Structure 3 (Inseparable - Object is a Clause or Long Phrase): Subject + look up + [object/information]
- Explanation: When the object is a longer phrase or a clause (e.g., starting with "what," "how," "when"), look up often remains together for clarity.
- Example 1: We should look up what ingredients are needed for this recipe.
- Example 2: She plans to look up how to get to the museum by public transport.
Tip: When you're unsure if you should separate look up with a noun object, keeping it together ("look up the word") is often acceptable, though separating it ("look the word up") is very common in spoken English. However, with pronouns, separation is mandatory.
Meaning 2: For a situation to improve or get better
When we say "things are looking up" or a situation is "looking up," it means that circumstances are becoming more positive, hopeful, or promising after a period of difficulty. In this sense, look up is intransitive (it doesn't take a direct object) and therefore inseparable.
Structure: Subject (e.g., things, business, my prospects) + look up
- Explanation: The subject is the situation or aspect that is improving.
- Example 1: After a slow start to the year, our company's profits are finally looking up.
- Example 2: My personal life is looking up now that I've moved to a new city.
Tip: This usage often carries an optimistic tone. It's a great phrase to use when you want to express that a previously bad or stagnant situation is showing signs of positive change.
Meaning 3: To visit or make contact with someone
This meaning involves seeking out and visiting someone, especially a person you haven't seen in a while or someone you know in a place you are visiting. With this meaning, look up is transitive and separable, similar to when searching for information.
Structure 1 (Separable - Noun Object): Subject + look + [person] + up
- Explanation: The person being visited is the object and can be placed between "look" and "up".
- Example 1: When I travel to London, I plan to look my old college friend up.
- Example 2: He promised to look his aunt up the next time he was in her town.
Structure 2 (Separable - Pronoun Object): Subject + look + [pronoun object: him, her, them] + up
- Explanation: If the object is a pronoun, it must go between "look" and "up".
- Example 1: "Have you seen John lately?" "No, but I should look him up."
- Example 2: My cousins are in the area; I must look them up this weekend.
Structure 3 (Inseparable - Object is a Noun): Subject + look up + [person]
- Explanation: While separable is common, it's also grammatically acceptable to keep "look up" together before the noun object, though it might sound slightly more formal or less common in casual speech for this meaning.
- Example 1: You really should look up your former mentor; she'd be delighted to hear from you.
- Example 2: We decided to look up an old teacher during our alumni visit.
Tip: This usage often implies a deliberate effort to reconnect. It's friendlier than just "visit" in some contexts, suggesting a renewal of contact.
