CONVERSION
What is Conversion?
Conversion is another easy and very common way English creates new words.
It means: You take a word and change its job (word class) without changing the spelling or pronunciation at all.
The word stays exactly the same — only its function changes.
Simple Example from Social Media:
Hashtag started as a noun: “A hashtag is really useful for starting a conversation.”
Then it quickly became a verb: “Some users find it annoying if people hashtag too much.”
Same word, different job — that’s conversion!
Most Common Types of Conversion:
Turning nouns into verbs (this is the most popular):
Julia Roberts co-starred with Hugh Grant. (co-star = noun → verb)
The critic rubbished the actor’s performance. (rubbish = noun → verb meaning “criticised strongly”)
I’ve programmed your lights to come on at eight. (program = noun → verb)
Jo had to elbow her way through the crowd. (elbow = noun → verb)
Turning verbs into nouns (also very common):
The thief made a quick lunge at the handbag. (lunge = verb → noun)
Martin took his old furniture to the dump. (dump = verb → noun)
Other types (less common but possible):
Adjective → noun: “She was his equal.”
Adjective → verb: “The athlete tried to better his previous performance.”
Even adverbs can sometimes become verbs: “The opposition tried to out the president.” (meaning to expose or remove him)
Interesting Point:
Sometimes it’s hard to know which version came first (noun or verb). For example, with the word bottle:
It must have started as a noun (the object).
Later it became a verb (“to bottle something”) because you can’t put something in a bottle if bottles don’t exist yet!
Why is conversion so useful?
English speakers love conversion because it’s fast and flexible. You can turn words into new jobs whenever you need them. Recent examples:
photobomb → works as both noun and verb almost from the beginning.
retweet → also appeared as both noun and verb at almost the same time.
Summary in one sentence:
Conversion is when we reuse the exact same word in a different grammatical role (e.g. noun → verb) without changing how it looks or sounds — and it happens all the time in modern English!
