series

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!
