series
A series is a group of things that come one after another in a specific order.
Explanation at your level:
A series is a group of things. Think of a TV show. It has many parts. Each part is one episode. Together, they make a series. You watch them one by one.
When you have many things that happen in a row, you call it a series. For example, 'I read a series of books.' This means you read the first book, then the second, and then the third. It is a group of related things.
In English, we use series to talk about a sequence. It can be a series of tests at school or a series of meetings at work. It implies that the items are connected or follow a specific order. Remember, the word stays the same if you have one or many.
The word series is often used to describe a structured sequence. In professional contexts, you might hear about a 'series of negotiations.' It is more formal than saying 'a bunch of.' In technical contexts, it describes a specific way of connecting items, like batteries in a flashlight.
At an advanced level, series is used to describe complex sequences, such as a 'series of events leading to a conclusion.' It is frequently used in academic writing to denote a logical progression. Note the distinction between 'sequence' (which emphasizes order) and 'series' (which often emphasizes the collection as a whole entity).
Mastery of series involves understanding its application in specialized fields like mathematics, where it refers to the sum of a sequence of terms. Culturally, it is deeply embedded in the concept of serialized media. Its etymological roots in 'binding' allow for nuanced usage in describing everything from logical arguments to physical electrical configurations.

Think of a series as a string of pearls; each pearl is distinct, but they are connected in a specific, linear order. When we use this word, we are usually highlighting that these items belong together as a group.
In your daily life, you encounter a series of events every morning: waking up, brushing your teeth, and eating breakfast. Each action follows the previous one. In science, especially electricity, the term takes on a very specific meaning. A series circuit is one where the electricity has only one path to travel. If one lightbulb burns out, the whole path is broken!
The word series comes directly from the Latin word serere, which means 'to join' or 'to bind.' It has been part of the English language since the early 17th century.
Historically, it was used to describe rows or chains of things. Because the Latin root implies 'tying together,' it makes sense that we use it today for everything from books in a collection to complex mathematical sequences. It is a classic example of a word that has kept its core meaning of 'connection' while expanding into technical fields like engineering and media.
You will hear series used in both casual and formal settings. In casual conversation, people often talk about a 'TV series' or a 'series of unfortunate events.' It is a very versatile noun.
Common collocations include 'a series of', which is the most frequent way to introduce a list of occurrences. In technical writing, you might see 'connected in series', which is the standard way to describe electrical components. Remember that series is both singular and plural; you have 'one series' and 'two series'.
While 'series' itself is often the subject of a sentence, it appears in many common phrases. 1. A series of: Used to describe multiple items (e.g., 'A series of mistakes'). 2. In series: Used in engineering to describe a specific connection type. 3. World Series: The famous baseball championship. 4. TV series: A show with multiple episodes. 5. Mathematical series: The sum of a sequence of numbers.
The most important thing to remember is that series ends in an 's' but is the same word for both singular and plural. You say 'This series is great' and 'These series are great'.
Pronunciation is tricky! In both British and American English, it is /ˈsɪəriːz/. It rhymes with 'queries' or 'theories'. The stress is always on the first syllable. Be careful not to pronounce it like 'serious'—that is a completely different word!
Fun Fact
It shares a root with the word 'sergeant'!
