1
general idea, not concrete
An idea about something that is not tied to one real thing or situation, but is very general.
Vzorec užití:
an abstraction of [something]
Častá chyba:
Learners often confuse "abstraction" with "abstract" meaning a short summary of a paper. An "abstract" is a summary text, while an "abstraction" is usually a general idea or the process of making ideas general. Learners may also overuse "abstraction" in casual speech where "idea" or "concept" would be more natural.
Synonyma
concept (More common and neutral; does not strongly suggest distance from concrete reality.)
|
notion (Slightly more informal and often less strictly defined than an abstraction.)
|
idea (Very general; can be concrete or abstract, so less precise in academic contexts.)
Antonyma
concrete example (Emphasizes a specific, real-world instance rather than a general, abstract idea.)

process of simplifying by generalizing
The way of making a system or idea simpler by hiding details and looking only at the main parts, often in subjects like math or computer science.
Vzorec užití:
abstraction in [field/subject]
Častá chyba:
Learners sometimes mix this meaning with the art meaning of "abstraction" or use it as a casual synonym of "idea." In technical contexts, "abstraction" usually means a designed way of hiding complexity, not just any general thought. They may also confuse "abstraction" with "abstract class" or other specific terms in programming, which are particular kinds of abstractions.
Synonyma
simplification (Focuses on making something easier, not necessarily on hiding or ignoring details in a structured way.)
|
generalization (Focuses on making broad rules from specific cases; close in meaning but less technical than "abstraction" in computing or math.)
Antonyma
implementation (In technical contexts, refers to concrete details and actual realization rather than a simplified, abstract view.)

Příklady
- Abstraction is essential in software engineering because it lets programmers manage complexity.
- The course teaches abstraction in mathematics, asking students to move from numbers to symbols and structures.
- Good interface design depends on the right level of abstraction for the user.
- Through abstraction, the model ignores small variations and focuses on overall trends.
- Object-oriented programming relies heavily on abstraction and encapsulation.
Učební příklady
- Abstraction helps programmers think about big problems without worrying about every small detail.
- In math class, we use abstraction when we talk about numbers in general, not about five apples or ten books.
- Abstraction makes it easier to change the system later, because low-level details are hidden.
- The teacher said that abstraction is a key skill in computer science.
- With abstraction, we create a simple model of a very complex thing.

3
state of being lost in thought
A state where someone is thinking so much that they do not notice people or things around them.
Vzorec užití:
in a state of abstraction
Častá chyba:
Learners may confuse this with the more common meaning of "abstraction" as an idea. This sense usually appears with prepositions like "in" ("in a state of abstraction") and often describes someone’s mental state, not a concept or theory.
Synonyma
absorption (Very close in meaning; can describe being deeply interested in something, not only lost in thought.)
|
preoccupation (Suggests strong focus on a worry or problem, whereas "abstraction" can be more neutral or dreamy.)
Antonyma
alertness (Emphasizes being fully aware and attentive, the opposite of being mentally distant.)

non-representational artwork
A painting or other artwork that does not show real things clearly, but uses shapes and colors in an abstract way.
Vzorec užití:
an abstraction in [medium]
Častá chyba:
Learners may think "abstraction" in art always means the general style, but it can refer to individual works ("three small abstractions"). They may also confuse this with the general-idea meaning; context about painting, shapes, and colors usually signals the art sense.
Synonyma
abstract painting (More specific and common in everyday language; clearly indicates the art form rather than the general idea of abstraction.)
|
nonrepresentational work (Technical art term that stresses the lack of recognizable objects.)
Antonyma
realist painting (A style that aims to show real objects accurately, the opposite of abstraction in art.)

formal removal of a resource
The act of taking something, usually a natural resource like water, away from its place or source, in a formal or technical context.
Vzorec užití:
the abstraction of [substance] from [source]
Častá chyba:
Learners may not recognize this as a technical, formal use and might try to use it in everyday speech where simpler words like "taking" or "using" are more natural. They may also confuse "water abstraction" with "water in the abstract," which is a different structure and meaning.
Synonyma
extraction (Very close in technical contexts; slightly more common in general use and for taking minerals, oil, or information.)
|
withdrawal (Can be broader and less technical; not limited to physical substances.)
Antonyma
replenishment (Focuses on adding or restoring resources rather than taking them away.)
