Theodoros and Mestor are both real Greek names, but they are not spelling variants of the same name. Theodoros means “gift of God,” while Mestor is an ancient Greek name meaning “adviser” or “counsellor.”
Have you ever seen two unusual names and wondered, “Which one is correct?” This happens often with ancient Greek names. A name may appear in different books, translations, or historical records, making it hard to know whether two spellings are variants or completely different names.
Theodoros and Mestor are a good example. At first glance, they may look like possible alternatives. They are not.
As an English teacher and language writer, I often see learners assume that unfamiliar names must be spelling variations. That can lead to a simple mistake: treating two separate names as if they were two forms of one word.
Theodoros is the Greek form of Theodore. It comes from Greek Theódoros and means “gift of God.” (Behind the Name)
Mestor, on the other hand, is an ancient Greek name associated with several figures in Greek mythology. The name comes from a Greek word meaning “adviser” or “counsellor.” (Wikipedia)
So, which should you use? The answer depends on the person, character, or historical figure you mean.

The Origin and Background of Theodoros or Mestor

- theos — “god”

Together, they give the meaning “gift of God.” (Wiktionary)
The name has a long history. It was used in ancient Greece and later became popular in Christian communities because several saints carried the name. (Behind the Name)
The Greek form is also connected to several forms used in other languages.
For example:
- Greek: Theodoros

These are related forms of the same name. (Behind the Name)
Where does Mestor come from?

The name is connected with the Ancient Greek noun μήστωρ, meaning “adviser” or “counsellor.” (Behind the Name)
Mestor appears as the name of several men in Greek mythology.
One Mestor was the son of Perseus and Andromeda. Another was associated with Pterelaus, while another was a son of King Priam. Plato’s Critias also uses the name for one of the early princes of Atlantis. (Wikipedia)

For example:
Theodoros is a Greek sculptor.
If the person normally uses the English form, Theodore may be more suitable.
For English readers → Theodore may be easier
If you are writing for an English-speaking audience and the person is commonly known as Theodore, use that form.
For example:
Theodore Roosevelt
You would not normally change his name to Theodoros just because Theodore has Greek roots.
For Greek mythology → use Mestor when the character is Mestor
If you are writing about the mythological figure, use Mestor.
For example:
Mestor was one of the sons of Perseus and Andromeda.
Do not replace Mestor with Theodoros.
For global or academic writing → follow the source

Common Mistakes with Theodoros or Mestor
These names can cause several types of mistakes.
| Mistake | Correction | Why? |
|---|---|---|
| Calling Mestor a spelling of Theodoros | Treat them as separate names | They have different origins |
| Writing Theodoros when referring to a mythological Mestor | Use Mestor | Mestor is the character’s name |
| Assuming Theodore and Mestor are related | They are not equivalent names | Their meanings and roots differ |
| Changing a person’s Theodoros to Mestor | Keep the person’s actual name | Personal names should not be replaced |
| Treating Theodorus and Mestor as variants | They are different names | Theodorus is related to Theodoros |
Mistake 1: Thinking they are spelling variants
❌ Theodoros or Mestor are two spellings of the same name.
✅ Theodoros and Mestor are separate Greek names.
This is the biggest mistake to avoid.
Mistake 2: Using Mestor as an English form of Theodoros
❌ The Greek form of Theodore is Mestor.
✅ The Greek form of Theodore is Theodoros.
Mestor is an entirely different name.
Mistake 3: Assuming every Greek name has one English spelling
Greek names can have several forms because they move between different alphabets and languages.
For example, Θεόδωρος can appear as Theodoros, Theodorus, or Theodore, depending on the language and context. (Behind the Name)
That does not mean Mestor belongs to the same group.
