Structure with Foul up

The phrasal verb "Foul up" can be used in a few different ways, depending on what you want to express. It's important to note that "Foul up" is often separable, meaning the object can come between "foul" and "up" or after "up."

Let's explore its main meanings and structures:

Meaning 1: To make a mistake; to spoil, ruin, or bungle something.

This is the most common usage of "Foul up". It signifies that someone has caused something to fail or go wrong.

Structure 1a: Subject + foul up + [object]

  • This structure implies that the subject directly caused the problem with the object.
  • Example 1: He fouled up the entire presentation with his nervousness.
  • Example 2: If you don't follow the instructions, you'll foul up the experiment.

Structure 1b: Subject + foul + [object] + up

  • This is the separable form, where the object is placed between "foul" and "up". This is very common, especially with pronoun objects.
  • Example 1: She fouled the recipe up by adding too much salt.
  • Example 2: I can't believe I fouled it up so badly.

Structure 1c: Subject + foul up (intransitive - no direct object, implying something went wrong generally)

  • Used when the focus is on the act of making a mistake, rather than what specifically was affected, or it's clear from context.
  • Example 1: He was given one simple task, and he still managed to foul up.
  • Example 2: We were so close to success, but then things started to foul up.

Meaning 2: To become or cause to become entangled, tangled, or jammed.

This meaning is often used in contexts involving ropes, lines, machinery, or systems that can get physically obstructed or stop working correctly.

Structure 2a: Subject + foul up + [object] (often referring to a system or mechanism)

  • The subject (often an external factor or the thing itself) causes the object to become jammed or entangled.
  • Example 1: The seaweed fouled up the boat's propeller.
  • Example 2: A build-up of debris can foul up the drainage system.

Structure 2b: [Object] + foul up (intransitive - the object itself becomes tangled or jammed)

  • Here, the object is the subject of the verb, indicating it became problematic on its own or due to unstated reasons.
  • Example 1: The fishing line fouled up as soon as I cast it.
  • Example 2: The printer keeps fouling up; I think it needs servicing.

Using "Foul up" correctly involves understanding these nuances. The context usually makes it clear whether you're talking about making a general mistake or a more physical entanglement or blockage. Paying attention to whether it's used transitively (with an object) or intransitively, and whether it's separated, will greatly improve your fluency.
