The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Dennis
of Dionysus
The Greek Dionysios means belonging to Dionysus, and it was an ordinary Greek personal name before any Christian carried it. The god is not incidental to the name; he is its whole content.
Dionysios → Denis → Dennis
How it traveled
Early Christians took Greek names as they found them, and a great many of them were theophoric — built on a god. Dionysios, Apollonios, Hermas, Demetrios and Olympias all came into the church attached to Olympian gods and stayed.
Dexter
'dyer' (one who dyes cloth), from the English surname; or 'right-handed, skillful' in Latin
The surname route is the documented one: Middle English *dexter*, *dyestere*, an occupational term for a dyer, originally a feminine agent noun in -ster that later applied to men too. Running alongside it is Latin *dexter*, 'on the right hand', hence 'skillful, favorable' — the root behind English *dexterity* and the heraldic *dexter* side of a shield. Both readings are genuinely attached to the name; the English trade word explains the surname, the Latin word explains much of the name's later appeal.
Old English dēag ('dye') → Middle English dyestere / dexter ('dyer') → Dexter (English surname) → Dexter (given name)
How it traveled
In medieval England, a dyer of cloth could be recorded as a *dyestere* or *dexter*, and the trade word became a hereditary surname in the way trade words often did — Baker, Fletcher, Webster. Surnames of that kind crossed to America and, in the nineteenth-century New England fashion for family names as first names, began appearing on baptismal and census records as given names.

Out loud, and in short
Dennis
DEN-iss
Two syllables with the weight at the front. French says duh-NEE with the final consonant silent, and Russian keeps the s.
- Den — Cut to one syllable; the standard everyday form in Britain.
- Denny — The affectionate form; a standing name of its own in America.
Dexter
DEK-ster
Stress on the first syllable. It has one pronunciation everywhere in English, and the spelling gives it away on sight.
- Dex — The standard short form, used informally and increasingly given on its own as a full first name.
- Dexy — A family-and-childhood diminutive rather than an adult one.

The trade-offs, name by name
Dennis
Strengths
- Everyone can spell it and say it on first hearing.
- It has a form in French, Italian, Spanish, Russian and Polish.
- It has an unbroken run in American records from the first year they were kept.
To consider
- It is strongly associated with the middle of the twentieth century.
- One long-running comic strip has attached a particular boy to the name.
- Denis with one n is standard in France and will be written for you.
Dexter
Strengths
- Comes with Dex built in — a one-syllable short form that works from the playground through a working life, and that stands alone as a name in its own right.
- Spelled the way it sounds; almost no one will need it repeated or corrected.
- On American birth records continuously since such records began, so it reads as familiar rather than newly coined.
To consider
- The Showtime series *Dexter*, which ran from 2006 and starred a blood-spatter analyst who was also a serial killer, is the association many adults reach for first. It has faded with time, but it has not disappeared.
- The cartoon *Dexter's Laboratory*, from the mid-1990s, gave the name a boy-genius-in-glasses image for a whole generation of viewers — harmless, but it is out there.
- It is stepping back gradually from its high point rather than rising, so it sits in the quieter middle of the register: known to everyone, common nowhere.
