Origin: Latin suffix -ive
Subjective has 3 different meanings across 1 category:
of a mental act performed entirely within the mind
"a cognition is an immanent act of mind"
Formed, as in opinions, based upon a person's feelings or intuition, not upon observation or reasoning; coming more from within the observer than from observations of the external environment.
"The critic argued that his review was too subjective because it relied entirely on his personal mood rather than an objective analysis of the film's technical merits."
In plain English: Subjective means based on your own personal feelings, thoughts, and opinions rather than facts that everyone agrees on.
"Whether that restaurant is good depends on your own taste, which makes food quality subjective."
Usage: Use subjective to describe judgments that rely on personal feelings rather than objective facts. This term is often contrasted with "objective," which refers to information free from individual bias.
The word comes from combining "subject" with the suffix "-ive." It originally meant something that is related to or characteristic of a subject.
