Jasean
Masculine
Seán is the regular spelling and Sean is the irregular one. Irish orthography is systematic — the accent marks a long vowel, and the vowel pairing follows a rule — while English has three attempts at the same word, Sean, Shaun and Shawn, none of which follows any rule at all.

Our story of Jasean
English speakers treat Irish spelling as an obstacle, and it is worth turning that round. Seán is written exactly as Irish rules require: the fada over the a marks a long vowel, and the e before the a is there because Irish requires the vowels flanking a consonant to agree in quality — the rule that also gives Iain its extra i. Every letter is doing a job. English, meeting the name without the rules, produced Sean, which an English reader will say wrong; Shaun, which is closer; and Shawn, which is closest and looks least like the original. Three spellings, none systematic, all trying to do what one accented vowel already did. American compounds then build on whichever of the three a family prefers, giving Jasean, Jashaun and Jashawn. Jasean peaks in 2000.
Meaningnot established
Not established
No inherited meaning as a compound. Ja- is a created American prefix. Seán is the Irish form of John, from French Jehan, from Latin Iohannes, from Hebrew Yohanan, Yahweh is gracious. The base name has a settled meaning; the compound does not, and Jasean has no documented reading.

Line the two peaks up, and Frederik's path sketches the road Jasean is walking now.
