Isabelle
Feminine · “my God is an oath”
Isabelle is overwhelmingly a girls’ name — 107,762 girls against 20 boys since 1880.
Isabelle is the French shape of a name that started out as Elizabeth and then walked away from it — the opening syllable dropped somewhere in medieval Spain and southern France, and the remainder became a name in its own right. It has three easy syllables that end on a soft bell of a sound, and it has been spoken in French, Spanish, Italian, German and English for something like eight hundred years.

Where it comes from
From Elisheva to Isabelle
The story of Isabelle
The Hebrew Elisheva reached Europe as Greek Elisabet and Latin Elisabeth, and in medieval Spain and Occitan-speaking southern France speakers trimmed the front of it: Elisabel, then Isabel. French took that and added its own ending, giving Isabelle, and by the high Middle Ages the two names were used side by side as though unrelated. Isabelle crossed into English with Norman and later French influence, and Scotland kept its own written form, Isobel. In the twentieth century the French spelling traveled far on the strength of French cinema — Isabelle Adjani and Isabelle Huppert both became internationally known under it.
Meaning
my God is an oath — via Elizabeth
Isabelle descends from Hebrew Elisheva, the source of Elizabeth, usually read as "my God is an oath" or "pledged to God". Scholars differ on the second element, which some read as "seven" and so "abundance"; the "oath" reading is the standard one.

The Glenda test
Every popular name lives one long story — a climb, a peak, a slow settling back. Isabelle's later chapters haven't been written yet, so we borrowed them: Glenda climbed just as high around 1944, and its whole arc is on record. Line the two peaks up, and Glenda's path sketches the road Isabelle is walking now.
Isabelle is coming down from a big peak (#79 in 2007). This is the stretch of the cycle where a name starts to sound like the decade it ruled.

The trade-off
- Spelled and read correctly on sight by most English speakers, even though several sister spellings exist.
- Several long-established short forms — Izzy, Belle, Bella — so the child has real choices without inventing anything.
- Present in American records for as long as national name records have been kept, and still given to babies now.
- Also charts in England and Wales and in Canada, and recognizable in French, Spanish, Italian and German.
- Isabel, Isabella, Isobel and Isabelle all sound close and are all in real use, so "how do you spell that?" will be a lifelong question. It is a quick answer, but a frequent one.
- Bella and Belle are widely used as full given names in their own right, which means a shortened Isabelle may be assumed to be one of those instead.
- Most Isabelles alive in the US today are young adults rather than children, so the name currently reads as belonging to that cohort — though it has cycled in and out of use for well over a century and shows no sign of vanishing.
