submerge

Imagine a submarine slipping beneath the waves - that is the basic idea of submerge. It means to go underwater or to be covered completely by liquid. But the word is not only about water. You can also submerge yourself in work, a book, or a project, meaning you give it all your attention and shut out other things. Strong feelings can seem to submerge you too, when they take over your thoughts. A detective might submerge himself in a case, reading every report and following every clue until little else is on his mind.

To submerge means to put something under liquid, usually water, or to go under the surface so that it is completely covered. This is the most literal meaning of the word. You might use it for a diver going below the surface, a road disappearing in a flood, or a city covered by rising water: "The ancient city was submerged by rising sea levels."

But submerge can also be used figuratively. It can describe being fully taken over by a feeling, thought, or activity. When you submerge yourself in something, you give yourself to it so fully that other things fade into the background. "She submerged herself in her studies to escape the stress of her personal life." Here the idea is complete involvement, as if the activity closes over you.

The word often suggests that something is hidden, covered, or hard to notice because it has gone below the surface. In figurative use, it can also suggest being overpowered. "He was submerged by grief after the loss of his friend." This means the feeling was so strong that it seemed to cover everything else.

So whether it describes something going underwater, a person disappearing into work, or a mind overtaken by emotion, submerge points to the same core idea: something is covered over, drawn below the surface, or taken over so fully that it is no longer clearly separate.
