Definition

1. Adjective:
   • Not arising from natural growth or life processes; lacking organic structure: Describes substances, compounds, or matter that are not derived from living organisms and do not contain carbon-hydrogen bonds characteristic of living things.
   • Relating to or denoting compounds not containing carbon (with noted exceptions): In chemistry, pertains to substances not based on carbon chains or rings, such as minerals, metals, salts, and acids like sulfuric or hydrochloric acid. (Note: Some simple carbon compounds like carbonates are also traditionally classified as inorganic.)

Usage

• Used primarily in scientific contexts, especially chemistry, geology, and biology, to distinguish from "organic" matter.
• Can describe materials, chemistry, compounds, or processes.
• Often precedes a noun it modifies (e.g., inorganic material, inorganic chemistry).

Examples

• As an adjective:
  • Rocks and metals are examples of inorganic matter.
  • The laboratory specializes in inorganic chemistry, studying compounds like salts and minerals.
  • Fertilizers can be either organic or inorganic in origin.

Advanced Usage

• "inorganic growth": (Business/Economics) Expansion of a company achieved through mergers and acquisitions, rather than through increasing internal sales and output.
  • The corporation's rapid expansion was due to aggressive inorganic growth strategies.
• In a broader, sometimes figurative sense: Can describe something as artificial, foreign, or not an integral part of a system.
  • The new policy felt inorganic to the company's traditional culture.

Variants and Related Words

• Inorganically (adverb): In a manner not derived from living organisms.
  • The crystal formed inorganically in the geothermal pool.
• Inorganic compound (noun phrase): A chemical compound that is not an organic compound (e.g., sodium chloride, water, ammonia).
• Inorganic chemistry (noun phrase): The branch of chemistry concerned with the properties and reactions of inorganic compounds.

Synonyms

• Mineral: (when referring to non-biological, solid inorganic substances)
• Abiotic: Not associated with or derived from living organisms.
• Artificial: (in non-scientific contexts, implying human-made rather than natural)

Antonyms

• Organic: Of, relating to, or derived from living matter; in chemistry, containing carbon.

Notes on Meaning

• The core scientific meaning contrasts with "organic." The key distinction in chemistry is the absence of carbon-hydrogen (C-H) bonds, though the classification has exceptions (e.g., carbon dioxide is considered inorganic).
• It can imply a lack of the complex, organized structure found in living things.
