Adverbs are one of the spices of life, a word like “suddenly” is so serviceable in prose.
Suddenly reminds me of a bird story that plays out regularly. I am a most irksome neighbor. Given the passel of dove that loves my yard I so often damage their calm and send them into full throttle emergency dove take off. The scene is a blur of color; they explode into the air, and make that tinkling bell sound as they gain altitude. Off they roar into the protective branches of a pine tree still within sight of me, their heads bobbing, they eyeball me guardedly.
I have not become accustomed to their surprising aerial escapes nor have I stopped being amazed at how suddenly they forget all the bother from a few seconds ago. I hastily scatter some food and I disappear, then, they return, land, and un-scatter, perhaps still wary, and suddenly make the dove chow disappear from the grass.
Suddenly tells how something is accomplished. Suddenly soup is just not in my DNA. I admit one thing is better done quickly. Sticky bandages adhering to my mammalian skin I am looking at you.
I love slow brewed tea. I would be confused if sunsets were suddenly over. Floodwater suddenly receding from my door is fabulous.
Telling how something gets done is made suddenly easier by employing adverbs. Then, given a little time the other parts of speech can get to work and help the writer make something of meaning.
