Understanding the Phrasal Verb "Fatten Out"
In the world of English phrasal verbs, some expressions are incredibly precise, while others are used more casually to describe changes in size or appearance. One such term is fatten out. While it is not as common as "fill out" or "fatten up," it is still an evocative way to describe the process of something becoming fuller, thicker, or more substantial over time. Whether referring to livestock, business profits, or even a thin manuscript, understanding how to use fatten out will add a touch of descriptive flair to your vocabulary.
Meaning and Usage
At its core, fatten out means to become larger, wider, or more plump. While the word "fat" often carries a negative connotation when applied to humans, the phrasal verb fatten out is frequently used in agricultural or metaphorical contexts where the increase in size is seen as a sign of growth, health, or profitability.
You will most commonly encounter this phrase in the following contexts:
- Agriculture: Describing animals that are being prepared for market by increasing their body mass.
- Abstract Growth: Describing things like portfolios, bank accounts, or even creative projects that are gaining "substance" or detail.
- Physical Appearance: Occasionally used to describe something that is becoming less thin or gaunt as it fills with volume.
Grammar and Patterns
Fatten out is an intransitive phrasal verb. This means it does not typically take a direct object. You describe the subject itself "fattening out," rather than someone "fattening out" something else (for that, you would use "fatten up").
Examples of proper usage:
- The cattle tend to fatten out quickly once they are moved to the lush summer pastures.
- If you add more detail to your research paper, the slim argument will really fatten out.
- The company's profits began to fatten out after they launched their new product line.
Common Mistakes to Avoid
The biggest mistake learners make is confusing fatten out with fatten up. While they share the root word "fat," they are not always interchangeable.
Fatten up is usually transitive; you fatten something else up (e.g., "The farmer is fattening up the pigs"). Fatten out is almost exclusively intransitive; the subject is the one doing the growing (e.g., "The pigs are fattening out").
Another mistake is using the term to describe people. Because "fat" can be a sensitive topic, saying a person is "fattening out" can sound offensive or rude. It is much safer to use "filling out" if you are describing a person gaining a healthier, more robust weight.
