Structure with 'Let down'

Understanding the structure of "Let down" is crucial for using it correctly. This phrasal verb is separable, meaning the object can often come between "let" and "down," especially when the object is a pronoun. Let's explore its common meanings and their typical sentence structures to help you use "Let down" effectively.

Meaning 1: To Disappoint Someone

This is perhaps the most frequent and emotionally charged use of "Let down". When you let someone down, you fail to meet their expectations, hopes, or fail to provide the support they were relying on. This can happen in personal relationships, professional settings, or any situation where trust or expectation is involved. The feeling of being let down is often associated with sadness, frustration, or even a sense of betrayal.

• Key Idea: Failure to meet expectations or provide promised support.

• Separability: This phrasal verb is separable.

  • Noun object: You can say "He let his team down" or "He let down his team." Both are generally acceptable, though placing the noun object between "let" and "down" is very common, especially if the object is not too long.
  • Pronoun object: If the object is a pronoun (me, you, him, her, it, us, them), it must go between "let" and "down." For example, "He letmedown." You cannot say "He let down me."

• Structure 1 (Object is a noun): Subject + let + [object/person] + down

  • Example 1: His constant lateness really lets his colleagues down, as they have to cover for him.
  • Example 2: The company let its loyal customers down by discontinuing their favorite product without warning.
  • Additional Example: She felt her parents let her down when they missed her graduation ceremony.

• Structure 2 (Object is a pronoun): Subject + let + [pronoun object] + down

  • Example 1: I trusted him completely, but he let me down when I needed him most.
  • Example 2: "You promised you'd be here. Why did you let us down?" she asked, her voice trembling slightly.
  • Additional Example: We won't let you down; our team is fully committed to completing this project successfully.

• Structure 3 (Passive voice): Subject + to be + let down + (by someone/something) This structure is used when the focus is on the person or thing that is disappointed, rather than who or what caused the disappointment (though this can be added with "by").

  • Example 1: She felt terribly let down by his thoughtless actions and series of empty promises.
  • Example 2: The entire fanbase was let down by the team's poor performance in the final championship match.
  • Additional Example: After all his hard work and dedication, he was let down by the unexpected system failure during the presentation.

• Common Collocations:

  • To feel let down
  • To be badly/terribly/seriously let down
  • Don't let me down! (A plea or warning)

Meaning 2: To Lower Something Physically

This meaning of "Let down" is quite literal. It refers to the action of moving an object from a higher position to a lower one. It can be used for a wide variety of objects and is a straightforward application of the verb.

• Key Idea: To move something downwards.

• Separability: This is also separable. "Let the box down" or "Let down the box." With pronouns: "Let it down."

• Structure: Subject + let + [object] + down

  • Example 1: He carefully let the heavy suitcase down onto the luggage rack.
  • Example 2: Can you let the window blinds down a bit? The afternoon sun is too bright in here.
  • Additional Example: The rescue team slowly let a rope down to the stranded climber in the ravine.

This meaning also extends to specific contexts like hair or parts of clothing:

• Letting down hair: This means to unfasten or release hair that has been tied up or styled, allowing it to hang loosely.

  • Structure: Subject + let + one's hair + down
  • Example 1: After a long day at work, she finally let her long hair down and sighed in relief.
  • Example 2: "Just let your hair down and have some fun!" he told her, encouraging her to be less formal and enjoy the party.

• Letting down a garment (e.g., hem): In sewing or tailoring, this means to lengthen a piece of clothing, like a skirt or trousers, by unfolding and unpicking a hem or tuck.

  • Structure: Subject + let + [garment part] + down
  • Example 1: My mother had to let down the hem of my school skirt as I seemed to grow taller every month.
  • Example 2: The tailor suggested he could let the sleeves of the new jacket down by about an inch to fit perfectly.

Meaning 3: To Deflate Something (Allow Air to Escape)

"Let down" can be used to describe the action of releasing air from an inflatable object, causing it to deflate. While "let the air out of" is often more common and explicit for this meaning, "let down" can be used, particularly with tires.

• Key Idea: To cause something to lose air and collapse or become soft.

• Separability: Usually structured as "let the [object] down".

• Structure (for tires/inflatables): Subject + let + the + [object] + down

  • Example 1: The mechanic suspected a slow puncture, so he let the tyre down completely to inspect it more closely.
  • Example 2: Someone had maliciously let all my car tires down during the night, which was very frustrating.
  • Additional Example: Before packing the inflatable air mattress away, you need to let it down fully so it fits in the bag.

It's important to note the slight nuance: "to let the air out of a tire" is very clear. "To let a tire down" implies causing it to deflate, often intentionally or for a specific purpose.

Idiomatic Use: "Let one's hair down"

Beyond the literal meaning of untying one's hair, the phrase "let one's hair down" is a popular idiom in English. It means to relax, behave informally, and enjoy oneself without inhibition, especially after a period of restraint, stress, or hard work. This idiomatic usage of a phrase related to "Let down" highlights the richness of phrasal verbs.

• Structure: Subject + let + one's hair + down
• Example 1: The demanding conference was finally over, so everyone went to the evening party to let their hair down.
• Example 2: It's important to let your hair down and forget about work for a while when you are on vacation.
