Medusa
Medusa's name transparently means "guardian" or "protectress," one of the clearest etymologies in Greek myth and a striking irony given how she is remembered.

Meaning
The name Medousa (Μέδουσα) is among the more linguistically transparent names in Greek mythology, with little scholarly dispute about its formation. It is the feminine present participle of the verb medein, meaning "to protect," "to rule over," or "to take appropriate measures for," itself descending from the Proto-Indo-European root *med-, broadly meaning "to take appropriate measures" or "to measure out what is fitting." As a present participle, Medousa functions grammatically the way an English word like "guarding" or "ruling" would if used as a name - it literally means something like "the one who guards" or "the ruling one," actively rather than passively, describing an ongoing action rather than a fixed title. This same Proto-Indo-European root *med- is a remarkably productive one across the Indo-European language family, and it is worth noting how far its descendants spread: it underlies the Latin verb mederi ("to heal, to take medical measures") and its derivative medicus ("doctor"), which is the direct ancestor of the English words "medicine" and "medical." It also underlies Greek words related to counsel and ruling, appearing in names and titles built on the idea of exercising measured judgment or authority - a semantic cluster around "applying appropriate control or care," whether over a body, a people, or a place. What makes Medusa's case genuinely interesting to highlight, beyond the etymology's own security, is the gap between what her name literally means and how she is remembered in the myth and in later culture. A name built on "guardian" or "protectress" sits in real tension with her enduring popular image as a monstrous, deadly figure whose gaze turns onlookers to stone - an image shaped heavily by the myth's later tellings (especially Ovid's Metamorphoses, which frames her as a beautiful woman transformed into a monster after Poseidon violated her in Athena's temple, with Athena's anger then falling on Medusa rather than the god). Some scholars and mythographers have pointed to the name's protective root as evidence that Medusa may descend from an older, pre-Olympian figure with a genuinely guardian or apotropaic function - the Gorgon head (gorgoneion) was itself widely used across Greek art and architecture precisely as a protective device, mounted on shields, temples, and doorways to ward off evil, which fits a "guardian" etymology far better than it fits the later narrative of a punished monster. The name therefore preserves, in plain linguistic form, an older layer of meaning that the myth's most famous versions have largely obscured: not a monster to fear, but - at the level of the word itself - a protector.
What does the name Medusa actually mean?
Medusa means "guardian" or "protectress." It is the feminine present participle of the Greek verb medein, "to protect" or "to rule over," from the Proto-Indo-European root *med-, "to take appropriate measures." This is one of the more secure and transparent etymologies among Greek mythological names.
Why does Medusa's name mean "guardian" if she is remembered as a monster?
The name likely preserves an older layer of meaning from before the monstrous version of her story became dominant. The Gorgon head (gorgoneion) was widely used in Greek art as a protective emblem on shields, temples, and doorways to ward off evil - a genuinely guardian function that fits the name's root far better than the later narrative of a punished, deadly monster.
Does Medusa's name have anything to do with the word "meditate"?
The two are often assumed to be connected because they sound alike, but "meditate" descends from a different Latin root (meditari, related to measuring and reflecting), not directly from the same *med- lineage as Medusa's name and medicus. Any connection is more distant than it appears from spelling alone.
