The consonant letters of homorganic derivatives add one or two strokes to their base letters depending on their burst strength. By the ternary burst strength, continuant, occlusive and aspirated consonants complete their trilateral airstreams (TABLE 1). For example, ㄷ for [d] and ㅌ for [t] add a horizontal stroke for a stronger burst to ㄴ for [n] and ㄷ for [d], respectively. Remarkably, ㅂ breaks a stroke into two pieces and puts them on top of ㅁ like the horns creatively. ㅍ also breaks two strokes into twos and puts them beside ㅁ like a double wing.

DERIVED CLOSING SOUNDS
Reverse articulation of an opening sound, if possible, defines the closing sound whose letter reuses the opening letter (TABLE 3). Not all closing consonants of the homorganic derivatives are phonetically distinguishable but they are refreshingly principled. First, closing articulations of the aspirated nasal consonants (ㅍ, ㅌ, and ㅋ) diminish their phonations quickly and eliminate the distinctive phonetic features from their occlusive ones (ㅂ, ㄷ, and ㄱ). Second, like ㅇ and ㅅ, their closing derivatives behave the same way.
