Which prefix signifies "self"?

The prefix that signifies "self" is "auto-." This prefix is derived from the Greek word "autos," which translates to "self" or "by oneself." It is commonly used in various terms to indicate that something is performed by itself or is self-driven, such as "autonomous" (self-governing) or "automatic" (operating by itself). Understanding prefixes like "auto-" can enhance vocabulary and comprehension in language studies, especially in an education context where multi-sensory structured language is emphasized.

The other prefixes do not convey the same meaning. For example, "tele-" refers to distance, as in "telephone" (sound from afar), "hemi-" denotes half, seen in "hemisphere," and "hyper-" suggests excess or an overabundance, as in "hyperactive." Each of these prefixes has a distinct meaning, thus reinforcing why "auto-" is the correct choice when looking for a prefix that signifies "self."
