The story of Ygnacio
Ignis fatuus means foolish fire. It is the Latin name for the light that appears over marshes at night and leads travelers off the path into the bog, and every European language has its own word for it: will-o'-the-wisp, jack-o'-lantern, friar's lantern, the Welsh corpse candle. The folklore is uniform in treating it as malicious. The explanation usually given is spontaneous ignition of marsh gases, and it is not fully settled — the ignition mechanism is awkward, sightings have become very rare as wetlands were drained, and the phenomenon has almost never been produced under controlled conditions. What is certain is that the name calls the light foolish and means the traveler.
Meaningscholars disagree
possibly from fire
The Roman name may be Etruscan in origin and its meaning unrecovered. The connection to the Latin word for fire is a later association, encouraged by the spelling with a g and by the fervor attributed to the saint who made the name famous. Neither reading is secure.

Fashion outlook
Ygnacio 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
- Nacho comes off it as a ready-made and widely understood short form.
- The older Spanish spelling is genuine rather than invented.
- Every letter is said, so the spelling follows from the sound.
- Ignacio and Ignazio are both commoner and will be written for it.
- English readers treat the y as a consonant and stumble on the first syllable.
- The fire meaning is an association rather than a documented etymology.
