Most people know that if you do something in one fell swoop, you do it all at once. 

As in, “I sat down last night and made my website in one fell swoop.” 

But what does fell mean? And who is swooping?

As far as we know, this phrase was first written down by Shakespeare, in the play Macbeth. It’s spoken by the character Macduff, a Scottish thane, or clan leader. 

In the play, the thane Macbeth murders the king of Scotland and takes the throne for himself. When this happens, Macduff flees the country to seek a rival for the new king. He soon learns that Macbeth has killed his wife and children in revenge. 

When Macduff learns this, he cries out.

All my pretty ones? 
Did you say all? O hell-kite! All? 
What, all my pretty chickens and their dam 
At one fell swoop?

Let’s break this lament apart and see what it means.

The kite in “O hell-kite” refers to a bird of prey, like a hawk. 

Fell means fierce, savage, or dreadful. It comes from the Old French term fel, meaning evil.

Swoop has multiple meanings that could apply here. It can mean a blow, an act of clearing things away, or the act of descending from a great height.

A fell swoop thus describes the way a bird of prey might fall from the sky upon its quarry. Or a murderous thane fall upon his unwitting victims. 

Today, the phrase in one fell swoop has lost these dark connotations. It has a neutral meaning, free of any shades of dread.

So that’s your tidbit for today. To do something in one fell swoop means to do something quickly and all at once.
