Where it comes from

The story of Jannifer

Until the twentieth century the name was Cornish and almost nowhere else: local, unremarkable there, unknown in London. A playwright put it on a character in a play of the nineteen-hundreds, which was the first many English readers had seen of it, and from there it spread slowly and then very fast indeed, becoming for a stretch the most used woman's name in the English-speaking world. A county's local name became a global one inside sixty years. The respellings, of which this is one, arrived in the middle of that climb — the reliable sign that a name is being heard far more often than it is being read.

Meaningnot established

Not established

The name is the Cornish form of Guinevere, and Guinevere's own elements — usually read as white and smooth, or white and phantom — are argued over. Three steps of borrowing and a respelling separate this from that, and no meaning can be claimed with confidence.

Jannifer sits in the rare tail. Its best year on record was 1981, with 31 girls. Today it is given to few enough children that it does not enter the ranked charts at all.

Fashion outlook

Jannifer sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.

The trade-off

Practical strengths
  • The name behind it is universally recognized and easy everywhere.
  • It has warm, established short forms.
  • The spelling is rare while the name is completely familiar.
What to consider
  • Jennifer is the standard spelling and hers will be corrected to it constantly.
  • The altered vowel is inaudible, so the spelling must be given rather than said.
  • The name is strongly associated with particular decades.
