concrete
It is a tool for analysis of word meanings. Basically, words are placed higher or lower on the conceptual "ladder of abstraction" based on how they represent concrete or physical phenomena. Words that are higher on the ladder are more abstract than those that are lower.
At the top of the ladder of abstraction are concepts like ideas, philosophies, or theories, which are highly abstract and general in nature. These elements are removed from specific instances or details and tend to be overarching principles that govern more specific and concrete concepts lower on the ladder.
abstract and general the concepts become, moving away from concrete details and closer to overarching ideas.
Concrete words sit at the bottom of the ladder of abstraction. They are specific, tangible, and easily understood, representing objects or ideas that are physical or can be perceived through the senses. Examples include objects like "table" or actions like "running".
The "ladder of abstraction" is a comparison of words in terms of whether they apply to concrete phenomena (a coin) or to more abstract terms (wealth). The higher points on the ladder are the more abstract or general terms.
Concrete examples or specific instances would be used to identify elements at the top of the Ladder of Abstraction, as they are more specific and closer to reality.
Hierarchical decomposition helps break down complex systems into smaller, more manageable components, allowing us to focus on details at lower levels of abstraction. This process enables us to better understand, analyze, and design systems by iteratively addressing each level of abstraction.
From very high (the top) abstraction [down] to lower (more detailed) ones. Breaking a system into some smaller chunks, then for each chunks do more breaking or slicing.
As work moves outward on the spiral the product moves toward a more complete state and the level of abstraction at which work is performed is reduced (implementation specific work accelerates as we move further from the origin).

A combination ladder can be used in various configurations, such as an extension ladder, step ladder, or staircase ladder. It typically has adjustable locking mechanisms to secure it in the desired position. Users should always make sure the ladder is on stable ground and follow safety guidelines when climbing.
