With “verb”, a “doing word” is meant:
An adverb says to what extent.
Just how that works we quickly see
By taking out the word “quickly”.
“We see” remains but I must say
I really don’t know in what way
It is we see - quite fast or slow?
An adverb will ensure we know.
An adverb also often gives
An extra life to adjectives
By adding on the end “ly”
And there’s your adverb, home and dry.
E.g. from “slow”, we get “slowly”
How much easier can it be?
An adverb shapes a verb, it’s true,
But adjectives they can change too.
“They were quite angry” – here we might
Know less without the adverb “quite”.
