1
closely packed or thick
Having many things very close together, with little empty space.
사용 패턴：
a dense [noun]
자주 하는 실수：
Learners sometimes confuse "dense" with "intense" or "strong". "Dense" usually describes how full or crowded something is in space (dense forest, dense crowd), not how powerful it feels. Also, "dense" for crowded places is more common in writing; in everyday speech, people often say "packed" or "crowded".
유의어
thick (Very common general synonym for things like fog, hair, or forests; slightly more informal and broader in use.)
|
packed (Often used especially for people or objects in a space; suggests being uncomfortably full.)
|
crowded (Used mainly for people or vehicles, not usually for things like forests or fog.)
반의어
sparse (Standard opposite when things are spread out with a lot of empty space between them.)
|
thin (Opposite especially for things like hair, fog, or forests where there are few items in a given space.)
|
scattered (Emphasizes that items are spread out in different places rather than gathered together.)

2
having high physical density
Having a lot of matter in a small space, so it is heavy for its size.
사용 패턴：
[substance] is dense
자주 하는 실수：
Learners sometimes think "dense" here just means "heavy". In science, "dense" describes how much mass is in a certain volume, so an object can be small and dense but still feel heavy for its size.
유의어
high-density (More technical and explicit; often used in scientific or engineering contexts.)
|
heavy (Common word for weight; overlaps when something is heavy for its size but can be less precise scientifically.)
반의어
low-density (Technical opposite, describing materials with little mass in a given volume.)
|
light (Opposite in everyday speech when something does not feel heavy for its size.)

3
full of information and difficult
Having many ideas or too many words, so it is not easy to read or understand.
사용 패턴：
dense [text / book / article]
자주 하는 실수：
Learners may think "dense" always means "stupid", so they are surprised to see it describe books or texts. In this sense, "dense" is neutral and often positive or respectful, suggesting deep or serious content, not low intelligence.
유의어
complex (General word for something with many parts; does not always suggest that the writing is packed with information.)
|
heavy (Informal for writing that feels serious and hard to read; may also suggest an emotional tone.)
|
packed (Emphasizes that there is a lot of content in a small space, similar metaphor to "dense".)
반의어
simple (Describes writing that is easy to understand and not complicated.)
|
light (Often used for writing that is easy to read and not very serious or detailed.)
|
readable (Focuses on how easy and pleasant a text is to read.)

slow to understand; stupid
Not quick to understand; a little stupid.
사용 패턴：
[someone] is dense
자주 하는 실수：
Learners sometimes use this meaning of "dense" in formal writing, where it can sound rude or childish. It is better kept for informal speech. Also, "dense" about a person does not mean they are physically heavy; it only refers to mental ability.
유의어
slow (Informal for someone who takes a long time to understand; usually less rude than directly calling someone stupid.)
|
thick (Very close in meaning and tone; British English, quite informal and can be rude.)
|
dim (Informal, suggests low intelligence but often slightly softer than "stupid".)
반의어
bright (Informal compliment meaning intelligent or quick to understand.)
|
sharp (Suggests quick mental ability and understanding.)
|
smart (Common everyday opposite, especially in American English.)

mathematical dense set property
In math, used for a set of points where you can always find a point from that set as close as you want to any point in the space.
사용 패턴：
a dense [set / subset]
자주 하는 실수：
Learners may try to connect this directly to the everyday meaning of "crowded". While related by metaphor, in mathematics "dense" has a precise definition about points being arbitrarily close, not just many points in a region.
유의어
everywhere-approximating (Non-standard explanatory phrase sometimes used informally to explain the idea of denseness in math.)
반의어
discrete (In many mathematical contexts, describes sets where points are isolated rather than dense.)
