1 The point against which a lever is placed to get a purchase, or on which it turns or is supported.
1.1 A thing that plays a central or essential role in an activity, event, or situation.
Late 17th century (originally in the general sense ‘a prop or support’): from Latin, literally ‘post of a couch’, from fulcire ‘to prop up’.
Though Joe didn’t think about it, the mechanics of his digging involved his right hand providing a fulcrum point as the dirt came up on the shovel.
Without it, almost nothing happens.
No matter how hard they push,
Far right and, equally, far left
Accomplish little without
The fulcrum of compromise.
