The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Alessia
defender, helper
From the Greek verb alexein, 'to defend, to ward off' — the same root behind Alexander, Alexandra and Alexis.
alexein (Greek: to defend) → Alexios → Alessio → Alessia
How it traveled
The root is Greek: alexein, to defend, which produced the personal name Alexios. It traveled into Italian as Alessio, losing the Greek -x- to the softer double s that Italian prefers, and Alessia is its feminine counterpart.
Serena
calm, clear, tranquil
From Latin serenus, used of cloudless skies and untroubled water; the same root gives English serene.
serenus (Latin, 'clear, calm') → Serena (Roman name) → Serena
How it traveled
The Latin adjective serenus described bright, still weather, and by the Roman imperial period it had become a personal name. One documented bearer was Serena, niece of the emperor Theodosius I and wife of the general Stilicho, at the turn of the fifth century.
Where a reading is contested the note says so — this page does not turn a guess into a fact. The chain is each name's recorded forms, oldest first; the story is its opening, told in full on the name's own page.
Out loud, and in short
Alessia
ah-LESS-ee-ah
That is the Italian pronunciation, and the most common one in the US. Some English speakers reduce it to uh-LEH-shuh, closer to Alicia, so expect to state your preference more than once.
- Ale — The standard Italian short form, said AH-leh; it serves Alessia and Alessio alike and stays informal.
- Lessi — Informal English-language clipping of the second half; also spelled Lessie.
- Ally — Informal, and shared with Allison, Alexandra and Alice — it stands alone as a given name too.
- Sia — Informal short form taken from the ending; also exists independently as a name.
- Also Essie.
Serena
suh-REE-nuh
Italian and Spanish speakers say seh-REH-nah, with the middle vowel like the 'e' in 'bed'. Both are correct for the same name; it is worth deciding which one your family will use.
- Rena — The most established short form; also used on its own as a given name in English, German and Hebrew contexts.
- Sera — Informal clipping of the first syllables; overlaps in sound with Sarah, which can cause a moment's confusion.
- Sere — Common in Italian usage, said SEH-reh rather than rhyming with English 'sear'.
- Reni — Affectionate family form built from Rena, mostly used at home rather than on paper.

The trade-offs, name by name
Alessia
Strengths
- The meaning is settled and easy to give in three words: defender, helper.
- Close cousins Alexis, Alexia and Alexandra are already familiar to English speakers, so the name is rarely heard as unplaceable.
- Spelled as it is in Italian, with recognized forms in Romanian, Spanish, French and German — it travels without needing to change.
To consider
- It sits in a crowded neighborhood of similar spellings — Alicia, Alesia, Alexia, Alessa — and will be misheard or misspelled fairly often. A quick 'Alessia, with a double s' becomes routine.
- Two pronunciations compete: the Italian ah-LESS-ee-ah and an Anglicized uh-LEH-shuh. Both are used in the US, so it is worth deciding early which one your family will correct people to.
- The name is on a clear upward path, so a child born now may meet more Alessias as a teenager than she does in kindergarten — still nowhere near the crowd around the top-ten names.
Serena
Strengths
- Spelled the way it sounds in English, and already familiar to readers as the word serene — rarely needs repeating or clarifying.
- Written identically in Italian, Spanish, Portuguese and German, so it crosses borders without changing shape.
- A documented record stretching from Roman antiquity through Elizabethan poetry to the present day.
To consider
- For many people in the US the name belongs first to one extraordinarily famous tennis player. That is a warm association rather than a difficult one, but it is a strong one, and it will come up.
- The meaning is unusually transparent, so expect remarks about calmness and serenity from strangers for years — pleasant enough, but relentless.
- Serina, Sarina and Sirena all exist and sound close, so occasional misspellings are likely even though the name itself is easy to say.

Alessia is climbing fast right now. Steep climbs tend to come with steep descents — the quicker a name arrives, the more firmly it belongs to its moment.
Serena
30%chance Serena feels dated by 2040
Serena is on its second act. Revived names age gently: the generation that wore them first is far enough away that the name feels classic rather than dated.
