This document is an addendum / errata to @Hildt2018, which should be read first.
In section 2.2.8 Constraints on affixed particles, the article states that the only combination of affixes is འིའོ, but the Kangyur and Tengyur contain other combinations, particularly འིའམ. After discussing with grammar teachers, it seems the following combinations, although unlikely, would be correct:
འིའོའིའམའིའངའོའམའོའངའིའོའམའིའོའང
Note that these new particles do not affect the syllable decomposition algorithm described in section 3 Decomposing a syllable.
