Theorize vs. Theory — What's the Difference?

To formulate theories or a theory; speculate.

A theory is a rational type of abstract thinking about a phenomenon, or the results of such thinking. The process of contemplative and rational thinking is often associated with such processes as observational study or research.

To propose a theory about.

A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.

To formulate a theory, especially about some specific subject.

The branch of a science or art consisting of its explanatory statements, accepted principles, and methods of analysis, as opposed to practice

To speculate.

A set of theorems that constitute a systematic view of a branch of mathematics.

To form a theory or theories; to form opinions solely by theory; to speculate.

Abstract reasoning; speculation

To believe especially on uncertain or tentative grounds;

A belief or principle that guides action or assists comprehension or judgment

Construct a theory about;

An assumption based on limited information or knowledge; a conjecture.

Form or construct theories;

A description of an event or system that is considered to be accurate.

(sciences) A coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed, or which sets out the laws and principles of something known or observed; a hypothesis confirmed by observation, experiment etc.

(uncountable) The underlying principles or methods of a given technical skill, art etc., as opposed to its practice.

(mathematics) A field of study attempting to exhaustively describe a particular class of constructs.

A hypothesis or conjecture.

A set of axioms together with all statements derivable from them; or, a set of statements which are deductively closed. Equivalently, a formal language plus a set of axioms (from which can then be derived theorems). The statements may be required to all be bound (i.e., to have no free variables).

A doctrine, or scheme of things, which terminates in speculation or contemplation, without a view to practice; hypothesis; speculation.

An exposition of the general or abstract principles of any science; as, the theory of music.

The science, as distinguished from the art; as, the theory and practice of medicine.

The philosophical explanation of phenomena, either physical or moral; as, Lavoisier's theory of combustion; Adam Smith's theory of moral sentiments.

A well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena;

A tentative theory about the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena;

A belief that can guide behavior;
