B1 Adverb #16 most common 4 min read

highly

Highly means to a very large amount or degree.

Explanation at your level:

You use highly to say 'very' or 'a lot.' If you like a movie, you can say, 'I like this movie highly.' It means you think it is great. It is a good word to make your sentences stronger. Use it when you want to show you have a big opinion about something. It is easy to use: just put it before the word that describes the thing you like.

At this level, you can use highly to describe qualities. For example, you might say someone is highly intelligent. It is more formal than 'very.' You can use it when you talk about work, school, or your hobbies. It is a very common word in English, and using it will make you sound more like a native speaker when you give your opinion on things you enjoy.

As you move to intermediate English, you will see highly used in professional contexts. It is a great alternative to 'very' or 'extremely' when you want to sound more precise. We use it with adjectives like 'recommended,' 'likely,' or 'effective.' It shows that you have a good grasp of how to emphasize your points in a discussion or a written report.

At the B2 level, you should notice how highly functions as a degree adverb. It is often used in collocations that are fixed in English. For instance, we say 'highly controversial' or 'highly sensitive.' It adds a layer of sophistication to your arguments. You can use it to express strong degrees of probability or quality in both formal writing and spoken debates.

In advanced English, highly is used to nuance your claims. It is often found in academic or professional writing to indicate a high degree of certainty or intensity. You might encounter it in phrases like 'highly sophisticated systems' or 'highly nuanced arguments.' It allows you to avoid repetition of simpler intensifiers like 'very' and helps you maintain a professional, academic tone throughout your work.

At the mastery level, you understand that highly is about precision. It is used to describe states that are at the upper end of a spectrum. Whether it is 'highly volatile markets' or 'highly esteemed colleagues,' the word serves to elevate the register of your language. It is a staple in high-level discourse, helping you convey subtle shades of meaning that distinguish a fluent speaker from a master of the language.

Word in 30 Seconds

  • Used to mean 'very' or 'to a great degree'.
  • Pairs well with adjectives and past participles.
  • Common in professional and academic writing.
  • Not for use with physical size or color.

Welcome to the world of highly! Think of this word as a volume knob for your adjectives. When you want to say something is just 'good,' that is fine, but when you want to emphasize that it is truly excellent, you reach for highly.

It is a versatile adverb that helps us express intensity. Whether you are talking about a highly complex math problem or a highly skilled athlete, this word adds weight and importance to your message. It is a fantastic tool for making your English sound more descriptive and precise.

You will notice that we often use it before adjectives that describe quality or ability. It is not just a filler word; it tells the listener that the degree of the quality is significant. Using it correctly helps you communicate your enthusiasm or the severity of a situation clearly and effectively.

The history of highly is quite straightforward and rooted in Old English. It comes from the word heah, which meant 'high' in a physical or metaphorical sense. Over centuries, the suffix -ly was added to turn the adjective 'high' into an adverb.

In its earliest forms, it was used to describe physical height, but as the English language evolved, the meaning shifted toward abstract concepts. By the Middle English period, it was commonly used to mean 'in a high manner' or 'to a great degree.' It is fascinating to see how a simple word about climbing a mountain became a word about describing how smart or talented someone is!

It shares roots with other Germanic languages, such as the German hoch. While languages change, the core idea of 'elevation'—whether it is a mountain or a level of skill—remains the heartbeat of this word. It has stood the test of time, remaining a staple in our vocabulary for hundreds of years.

Using highly is all about pairing it with the right partners. We don't say 'highly big' or 'highly blue'; instead, we use it with adjectives that imply a scale of quality or intensity. Common pairs include highly recommended, highly likely, and highly effective.

In terms of register, highly is very flexible. You can use it in a casual conversation with friends, like saying 'That movie is highly entertaining,' or in a formal business email, such as 'We highly value your partnership.' It is considered standard English and fits almost any context.

Remember that it is almost always placed before the adjective it modifies. If you are ever unsure, try replacing it with 'very' or 'extremely.' If the sentence still makes sense, you are likely using it correctly! It is a safe, professional, and powerful word to keep in your daily vocabulary toolkit.

While highly itself isn't the core of many set idioms, it appears in several fixed expressions that native speakers use constantly. Here are a few to boost your fluency:

  • Highly recommended: Used when you really want someone to try something. 'I highly recommend this book.'
  • Highly thought of: Means someone is respected. 'She is highly thought of in the industry.'
  • Highly strung: Describes someone who is very nervous or sensitive. 'He is a bit highly strung before exams.'
  • Highly placed: Refers to someone in a powerful position. 'The rumor came from a highly placed source.'
  • Highly visible: Something that is very easy to see or notice. 'The new policy is highly visible to all staff.'

Grammatically, highly is an adverb. Its primary job is to modify adjectives or past participles used as adjectives. It is not used to modify nouns. The pronunciation is simple: /ˈhaɪli/. The stress is on the first syllable, 'HI-lee.'

In British and American English, the pronunciation is virtually identical. A common mistake is to confuse it with 'high,' which is the adjective form. Remember: 'The mountain is high' (adjective), but 'The mountain is highly dangerous' (adverb modifying the adjective).

It rhymes with words like 'slyly,' 'wryly,' and 'shily.' Because it ends in 'ly,' it is easy to mistake for an adjective, but always check if it is describing an action or a quality. Keep your stress on the first syllable to sound natural and clear to native speakers.

It evolved from the word 'heah' which meant physically high.
