1
process of taking in substances or energy
The process when something like water, gas, light, or sound goes into another thing and is held inside it.
用法模式：
the absorption of [substance/energy] by [material]
常见错误：
Learners sometimes confuse "absorption" with the incorrect form *"absorbation". Use the noun "absorption" for the process, and the verb "absorb" for the action (e.g., "the absorption of water" vs. "the cloth absorbs water"). Another common confusion is between "absorption" and the technical term "adsorption"; in everyday English, "absorption" is almost always the correct choice.

state of being deeply engrossed
A state in which you are so interested in or busy with something that you do not notice other things around you.
用法模式：
absorption in [activity/thought/work]
常见错误：
Learners sometimes confuse this meaning with the physical process of taking in liquids or light. When "absorption" is followed by "in" plus an activity (e.g., "absorption in her work"), it usually refers to mental focus, not a physical process.
近义词
engrossment (Very close in meaning, but slightly more formal and less common in everyday speech.)
|
immersion (Often suggests very deep involvement, sometimes with learning or experience, not just momentary focus.)
反义词

incorporation into a larger whole
The process when a smaller group, company, or area becomes part of a bigger one and is no longer separate.
用法模式：
absorption of [group/organization/area] into [larger body]
常见错误：
Learners may mix this sense with the physical meaning. In this sense, "absorption" usually refers to groups, companies, or cultures, not liquids or light. Look for objects like "company", "village", or "refugees" to identify this meaning.
近义词

including indirect costs in product cost
In accounting, the way a company puts part of its general costs (like rent and utilities) into the cost of each product or service.
用法模式：
absorption of [costs/overheads] into [product cost/prices]
常见错误：
Learners may think "absorption" here still refers to a physical process. In business texts, when it appears next to words like "costing", "overhead", or "fixed costs", it refers to an accounting method, not liquids or light.
近义词
allocation (A broader accounting term; "absorption" is a specific way of allocating indirect costs into product costs.)
反义词
direct costing (An accounting method that does not absorb all fixed overheads into product cost, contrasting with absorption-based methods.)
搭配
