Phonograms 

Phonograms are 'the sound writing' signs to represent the sounds of the word rather then picture objects. They are either a (uniliteral) (biliteral) (triliteral). For an example the uniliteral /t/ and /r/ the 2 glyphs on end of the word for divinity /nTr/ 𓊹𓏏𓂋

​𓊹 on its own represents /nTr/ "god" , but then you add the two glyphs /t/𓏏 and /r/𓂋 it is to help spell out the word.
​

𓅓 /m/ "of"-  /m/ (Uniliterals)

​𓂋𓈖  /rn/ "mame" - 𓂋 /r/ + 𓈖 /n/  (Biliteral) 

𓋹𓈖𓐍 /anx/ "life" - 𓋹 /anx/ + 𓈖 /n/ + 𓐍 /x/   (Triliterals)
