## DIN 31635 Arabic (2026-10-29)

din-ara-Arab-Latn-31635-2011 (59 tests), section 6 over vocalized input:
Table 1 in full; short-vowel signs; fathatan as -an; sukun stripped first
(keeps the article rule adjacent); shadda doubling for every consonant with
mark-order swaps; hamza carriers contribute nothing (a+damma-carrier renders
only the mark's vowel); alif/hamza omitted word-initially; madda per rule f;
taa marbuta h-after-long-a with the lookbehind accepting BOTH the raw alif
and the merged a-macron (the long-vowel merge rules run first and consume
the alif — first-order lesson from the Hebrew mark-order negative); the
word-initial article with sun-letter assimilation and hyphen including the
doubled shadda form (aš-š). Reading-side documented: unvocalized waw/ya,
hamzat al-wasl, article elision after vowel-final words, construct state,
Allah.
