Structure with Be off of

The phrasal verb "be off of" generally follows a straightforward structure, though its acceptance varies among grammarians. It's important to note that the "of" is sometimes considered redundant, and "be off" can often convey the same meaning, especially in more formal contexts or British English. However, "be off of" is undeniably present in spoken English, particularly in North America.

Here are the common meanings and their structures:

Meaning 1: To have stopped consuming or using something (especially a substance, medication, or type of food).

This is perhaps the most common usage of "be off of". It indicates a conscious decision to abstain from something that was previously consumed or used regularly.

  • Structure: Subject + to be (verb) + off + of + [Noun/Noun Phrase (the substance/item)]
  • Example 1: After the doctor's advice, John decided he needs to be off of sugary drinks for a month to improve his health.
  • Example 2: She's trying to be off of caffeine entirely because it was causing her anxiety and affecting her sleep patterns.

Meaning 2: To no longer be under the influence or effect of something.

This meaning is closely related to the first but focuses more on the state of not being affected by something, often medication or a temporary condition.

  • Structure: Subject + to be (verb) + off + of + [Noun/Noun Phrase (the influence/effect/medication)]
  • Example 1: He felt much clearer and more energetic once he was off of the strong painkillers prescribed after his surgery.
  • Example 2: It took a few days for her system to feel completely normal after being off of the medication she had taken for years.

Meaning 3: (Less common, more informal) To have moved away from or dismounted from something.

While "get off of" or simply "be off" are far more standard for this meaning, you might occasionally hear "be off of" in highly informal, colloquial speech, particularly referring to physical position.

  • Structure: Subject + to be (verb) + off + of + [Noun/Noun Phrase (the surface/vehicle/place)]
  • Example 1: "Make sure the cat is off of the kitchen counter before you start preparing food," she reminded him. (More common: "is off the counter")
  • Example 2: Once the tired rider was off of the horse, he immediately led it to the trough for some water. (More common: "was off the horse")

A Note on "Be off" vs. "Be off of"

It's crucial for learners to recognize that while "be off of" is heard, particularly in American English and informal speech, many grammarians and style guides advocate for simply using "be off" when the preposition "of" is redundant. For instance, "He is off sugar" is often preferred over "He is off of sugar." Both forms exist, and understanding "be off of" prepares you for real-world English conversations where it's frequently used. The inclusion of "of" can sometimes add a slight emphasis or rhythm, particularly in spoken language, but the core meaning generally remains the same as "be off" in the contexts of abstention or cessation.

Understanding the phrasal verb be off of is important for learners aiming for a more nuanced grasp of informal English and regional variations. While striving for grammatically precise language is good, recognizing and understanding common usage like this is key to comprehension.
