How it's used

Literary in nature, this term is rarely used in casual, everyday speech. It is most commonly encountered in idioms or formal writing to describe abstract concepts like knowledge, time, or space. When used in conversation, it often carries a slightly poetic or philosophical tone.

Examples

Common phrases

the sea of knowledge is boundless

Common mistake

Learners often mistakenly use this to describe physical objects or quantities, but it is reserved for abstract or vast concepts. Do not use it to describe a large amount of physical items or a simple large space.
