They are – as you might well imagine – the building blocks in English language learning and teaching English.
The collection of words in a language is known as the vocabulary and when collected together they are listed in a dictionary.
Speaking linguistically, a word can be described as the smallest possible unit in a reply.
So for example, if someone asks you if you’d like some cake then you might reply:
This is a single word and fine. Anything smaller isn’t a word at all and makes no sense.
Words Spoken & Words Written
In written language words are separated by either a space or a punctuation mark:
I’d like some cake, please!
But in spoken language the words run together and can sometimes be difficult to separate. If we were to write the sentence above as it sounds then it would look something like this:
A word consists of one or more letters. The two most common single letter words are I and a. The longest word cited in the Oxford English Dictionary is pseudopseudohypoparathyroidism (a type of disease).
In many cases (including pseudopseudohypoparathyroidism) words are made up of a root (or stem) with one or more affixes. For example, taking the root walk, here are a few of the additional words we can make from it by adding affixes:
walk, walker, walking, walkable, unwalkable…
Number & Definition
So how many words are there?
There are still many questions remaining about words in terms of what actually constitutes a word. This means the question of how many words a language has remains debatable.
To take a few examples:
- Is dog the same word as dogs?
- Is Olympic the same word as olympic?
- Is lebensraum an English word? What about bungalow or apartheid?
- Is google a word?
Vocabulary – how many words are there? And how many do you know?
Compound Words – words made up of other words
Taboo Words – words not used in polite company
