Should Ait, Nait and Ould be family-name particles? (Youssef Ait Taleb gives middle 'Ait', family 'Taleb') #1249

parse("Youssef Ait Taleb") gives given 'Youssef', middle 'Ait', family 'Taleb'. Ait (also spelled Aït, and Nait/N'Ait; Tamazight "the people of") opens Amazigh family names in Morocco and Algeria. Ould and Ouled (Arabic "son of") open family names in Mauritania and Algeria: Ahmed Ould Salem gives middle 'Ould', family 'Salem'. None of them has a reading, in Latin or Arabic script (يوسف ايت الطالب gives middle 'ايت'; أحمد ولد سالم gives middle 'ولد'). None of them is a given name.

Measured (2026-11-08, config_diff.py score), each listed as a never-given clan particle (add("ait", kind="clan"), and the same for aït, nait, ould, ouled):

With all five words listed, ORCID FR gains 9 and breaks 1; ORCID GB and US and PatentsView GB and US break none.

Every broken ait row is a writer who put the family name in the given box (given AIT TALEB, family Youssef). Those names are written family-first, and P1's fold (a never-given particle opening the name) reads the whole name as the family: Ait Taleb Youssef gives family 'Ait Taleb Youssef' by default, and family 'Ait Taleb', given 'Youssef' under FAMILY_FIRST. That's the same cost every never-given particle has.

Together with el (#1240) and ben (#1248), ORCID MA goes from 84.06 to 96.12 (2,403 fixed / 34 broken), ORCID TN from 86.94 to 96.13, ORCID MR from 65.48 to 75.00 and PSC Moroccan from 84.08 to 97.05. GB, US, NL and BE stay flat or go up.

Questions:

• List ait, aït, nait and ould, ouled as never-given clan particles? In which file: a Tamazight file (ber/zgh) for ait/nait, and ar.toml for ould/ouled?
• Should Ould be a patronymic, so it fills R9 (the patronymic view)? In Mauritania it names the father (Ahmed Ould Salem = Ahmed son of Salem); in Algeria and Morocco it has become a fixed family name. ORCID boxes put it in the family either way.
• The Arabic-script ايت and ولد: list them beside the Latin spellings? (5 and 4 names among 394 + 117 Moroccan parliamentarians.)
