EN Suffix Words – Intro


en is an example of an English suffix. If we know the root word and the function of the suffix, we can easily increase our vocabulary. Let’s use the noun length for our first example:

length (noun) means – the size or measurement of something from one end to the other (how long something is)

  • The waist of my jeans is okay, but I’m not happy with the length. They are too short.

One function of the English suffix en is to change adjectives or nouns into verbs.
lengthen (verb) means – to make longer

long Different word forms:

long – adjective

  • An elephant’s nose is long.

long – adverb (used with time)

  • How long did you stay in New York?

lengthen – verb

  • My mom had to lengthen my suit pants as I grew taller.

long shot – idiom = something is unlikely

  • I’m going to apply for the new division manager job. Getting the job is a long shot but I want to try.

As I said above, one of the functions of the English suffix en is to change adjectives or nouns into verbs.
Be careful. The opposite of lengthen is shorten. Short is an adjective and length is a noun.

shorten (verb) means – to make shorter

The suffix EN A good teller can lengthen or shorten your pants to make them fit better.

    (Increase the level of security.)

Suffix EN examples (Nouns to Adjectives)

Another use for the English suffix EN is to change nouns to adjectives.

a suffix used to form adjectives of source or material from nouns


Adjectives made from material nouns with the adjective EN used to be more common in older English.
For example in William Shakespeare’s play ‘A Midsummer Night’s Dream’ we can find the quote:

  • “What hempen home-spuns have we swaggering here”

This line is an insult to the clothing of one of the characters. – Your clothes look like you made them yourself out of hemp. (hempen)

*Hemp is a plant that has been used to make paper, rope, textiles, clothing, and more for thousands of years. (LINK)

We no longer use the word hempen. Hemp is used as an adjective now by itself without the suffix EN.

  • Hemp rope applications include climbing, fishing, shipping, and horsemanship.”

Another Shakespeare story used the term wheaten wreath to mean a wreath made of wheat.

Source – The historical development of the suffix -en in English

The adjective wheaten is no longer used.

wreath – an arrangement of flowers and leaves, especially in the shape of a circle

Suffix EN Adjective examples

  • ashen
  • earthen
  • flaxen
  • golden
  • silken
  • woolen 
  • wooden

*Note – ashen and flaxen are used to describe a color. They do not mean made of ash or made of flax. 

The adjectives I hear and use most often are wooden and golden.

wooden – made of wood

  • I just bought a new wooden coffee table for my living room. It was on sale!
    (A wooden table is a table made of wood.)
English Suffix -EN 
wooden – made of wood

Golden can mean gold-colored.

  • My sister is tall with golden hair.

or made of gold

  • The princess was wearing a beautiful golden crown with diamonds and rubies.
    (The crown is made of gold.)
  • Indiana Jones found a golden statue in the ancient ruins.

Golden – Suffix Example

Golden is an adjective that can mean something is very good or valuable.

* Gold is a precious metal so things made of gold have value, they are expensive.

How we use this adjective is a little different so let me explain with some examples. 

  • In Japan, we have 3 national holidays in the same week at the end of April. We call this holiday Golden week because you can have a long holiday. It is rare to have 3 days off in the same week, so it’s great!

Another good example is when we have a good chance to do something. We call it a golden opportunity.

  • I will visit my wife’s parents this weekend. They can’t speak English so this is a golden opportunity for me to practice my Japanese.

Another example is an American boxing competition called the Golden Gloves. Golden Glove boxing competitions happen across the country.

  • Many cities and states around the U.S. have a Golden Glove tournament.

Usually, boxing gloves are not made of gold, so gloves that are golden are very special. Golden gloves show that the boxers are very skilled.

Gold is connected with the top position. If you finish in first place in an event or competition you receive a gold medal.
Even though we don’t say “golden medal” this may explain why golden has a special meaning.

We don’t see the suffix EN added to other materials like silver (silveren) or bronze (bronzen). They are missing the importance of being the best.
