Explanation at your level:
You use substantially when you want to say something is very big. If you have a small apple and a giant apple, the giant one is substantially bigger. It is a big word, so you will see it in school books more than in simple stories.
When you talk about numbers or changes, substantially helps you be clear. If the price of a toy goes from $10 to $50, the price has substantially increased. It is a useful word for showing that a change is important.
At the intermediate level, you can use substantially to compare things. It is very common in business or news. For example, 'The company grew substantially this year.' It sounds more professional than just saying 'a lot' or 'very much.'
In B2 English, you start using substantially to add nuance to your arguments. It is great for academic writing where you need to show you understand the scale of a problem. It pairs well with verbs like 'impact,' 'influence,' or 'change.'
At the C1 level, you use substantially to demonstrate precision. It is often used in formal reports to quantify data. For instance, 'The results differed substantially from our initial hypothesis.' It shows you can distinguish between minor variations and significant deviations.
Mastering substantially at the C2 level involves understanding its role in formal rhetoric and technical discourse. It is the hallmark of a sophisticated writer who can calibrate the intensity of their claims. Whether in legal documents or scientific journals, it serves as a precise marker of magnitude. Its etymological roots in 'substance' allow for subtle, almost philosophical applications when discussing the core nature of a shift or transformation.

Hey there! Have you ever needed to describe a change that was so big you couldn't just call it 'a little bit'? That is exactly when you use substantially. It is a fantastic adverb that tells your listener or reader that the difference or amount you are talking about is truly significant.
Think of it as a step up from 'a lot.' While 'a lot' is great for everyday chat, substantially carries more weight. It implies that the change is noticeable, important, and has a real impact on the outcome. Whether you are talking about a substantially lower price or a substantially improved performance, you are signaling that this isn't just a minor tweak—it is a big deal!
The word substantially comes from the Latin word substantia, which means 'essence' or 'substance.' Back in the day, it referred to things that had real existence or physical form. Over time, the meaning shifted from just 'having a physical body' to 'having a large or important quality.'
It entered Middle English through Old French in the 14th century. It is fascinating to see how a word that once meant 'solid matter' evolved into a word we use to measure the size or importance of changes in our modern world. It is a classic example of how language grows to meet our need for more precise ways to describe the world around us.
You will find substantially most often in professional, academic, or journalistic writing. It is the perfect word to use when you are writing a report, an essay, or giving a formal presentation. It helps you sound precise and authoritative.
Common word combos include substantially higher, substantially lower, substantially different, and substantially reduced. Notice how these all describe a shift or a comparison. Because it is a formal word, you might want to avoid using it when texting your best friend about what you ate for lunch, unless you are being intentionally funny!
While substantially itself isn't usually part of a fixed idiom, it is often used in set phrases that function like idioms in professional settings. Here are five ways it appears:
- Substantially the same: Meaning almost identical. Example: 'The two reports were substantially the same.'
- Substantially complete: Meaning almost finished. Example: 'The building project is substantially complete.'
- Substantially better: Meaning a clear improvement. Example: 'Our new software is substantially better.'
- Substantially reduced: Meaning a large drop. Example: 'The price was substantially reduced.'
- Substantially altered: Meaning changed in a big way. Example: 'His opinion was substantially altered by the news.'
Grammatically, substantially is an adverb, so it usually modifies verbs or adjectives. You will often see it placed before the word it is describing, like 'substantially increased.' It follows the standard English pattern for adverbs ending in '-ly' derived from adjectives ending in '-ial'.
Pronunciation can be tricky! In IPA, it is səbˈstænʃəli. The stress is on the second syllable: 'sub-STAN-sha-lee.' A common mistake is to swallow the 'sh' sound, so make sure to enunciate that clearly. It rhymes with words like 'essentially' and 'potentially,' which share that same rhythmic flow.
Fun Fact
It comes from the Latin 'substantia', which literally means 'that which stands under'.
Pronunciation Guide
