What Does “Determine” Mean?
Determine means to make a decision, discover a fact, establish the truth, calculate a value, or control an outcome. It is a verb with several related uses.
When determine refers to making a choice, it means deciding what should happen. A manager may determine which plan the team will follow.
When it refers to investigation, determine means discovering or confirming a fact. A doctor may determine the cause of a symptom, while a researcher may determine whether a theory is correct.

In another context, determine means influencing or controlling a result. Weather conditions may determine whether an event can take place. The sentence context shows whether determine means decide, discover, calculate, prove, or influence.
Meaning, Tone, and Context of “Determine”
Determine is a neutral to formal word. It commonly appears in academic writing, reports, instructions, business communication, legal discussions, scientific explanations, and professional decisions.
