half

A half is one of two equal parts that make up a whole thing.

Explanation at your level:

You use half to talk about two equal pieces. If you have one big apple, you can cut it into two pieces. Each piece is a half. You can also use it for time. If it is 2:30, we say it is half past two. It is very easy to use!

At this level, you start using half with quantities. You might say 'I want half a sandwich' or 'The shop is half price today.' It helps you explain that you only want a portion of something, not the whole thing. It is a very useful word for shopping and cooking.

You can now use half in more complex structures, like 'half the time' or 'half as much.' It is great for comparing things. For example, 'This car is half as expensive as that one.' It helps you express ratios and proportions clearly in everyday conversations.

At this stage, you encounter idiomatic expressions like 'half-hearted' or 'not half bad.' You will notice that half is often used to emphasize a lack of effort or to downplay a success. It adds nuance to your descriptions when you want to sound more like a native speaker.

In advanced English, half appears in abstract contexts. You might discuss 'half-truths' in a political debate or 'half-measures' in a business strategy. Using the word effectively here shows you can use simple vocabulary to describe complex, nuanced situations, which is a hallmark of high-level proficiency.

Mastering half at the C2 level involves understanding its historical weight and its role in literary devices. Authors use it to create symmetry or to highlight fragmentation in a narrative. You recognize that 'halves' is not just a plural, but a structural concept in literature, representing duality and the search for wholeness in the human experience.

Mot en 30 secondes

  • Half means 50%.
  • The plural is halves.
  • It is used for time and quantity.
  • It is a very common word.

Welcome! Let's talk about half. It is one of those words we use every single day without even thinking about it. When you have a whole object, like a pizza or an hour of time, and you split it into two identical pieces, each of those pieces is a half.

Think of it as the ultimate equalizer. Whether you are sharing a sandwich with a friend or checking the clock to see if it is half past three, you are using this word to describe balance. It is simple, yet it is the foundation of how we measure parts of a whole in our daily lives.

The word half has deep roots in Old English, coming from the word healf. It has been around for over a thousand years, evolving from West Germanic languages. It is closely related to the German word halb and the Dutch half.

Interestingly, in older versions of English, it could also refer to a 'side' or 'part' in a more general sense. Over time, it became strictly associated with the mathematical concept of dividing by two. It is a classic example of a word that has kept its core meaning through centuries of linguistic change.

You will see half used with nouns, adjectives, and even time expressions. We often say 'half a' (like half a cup) or 'a half' (like a half of the pie). It is very flexible and works in both casual kitchen talk and formal scientific papers.

Common pairings include half-time in sports, half-price during sales, and half-hearted when someone isn't really trying. Because it is so common, it fits perfectly in any register, from talking to your toddler to writing a professional report.

Idioms make language colorful! Here are five favorites:

  • Half-baked: An idea that isn't fully thought through.
  • Do things by halves: To do something incompletely or without effort.
  • Half the battle: The most difficult part of a task.
  • Better half: A playful way to refer to your partner or spouse.
  • Not half bad: A British way of saying something is actually quite good.

The plural of half is halves. Notice how the 'f' changes to a 'v'—that is a classic English spelling rule! In terms of pronunciation, the 'l' is silent in most accents, making it sound like 'hahf'.

It rhymes with calf, graph (in some dialects), and laugh. Remember, when you use it with a noun, you can say 'half the cake' or 'half of the cake'; both are grammatically correct and very common.

Fun Fact

The 'l' was historically pronounced but faded away in most dialects over time.

Pronunciation Guide

UK /hɑːf/

The 'l' is silent, and the 'a' is a long, deep vowel.
