Some consonants in some contexts are not written (but are understood to be present), such as word-initial "s-" and "-w" before a consonant, as in "pe-ma" for "sperma" (, "seed"). The "pe-", which was primarily used as its value "pe" of grid class CV, is here being used for "sper-". This was not an innovative or exceptional use, but followed the stated rules. Syllable-final "-l", "-m", "-n", "-r" and "-s" are also not written out, and only word-final velars are notated by plene writing: "a-to-ro-qo" for "anthrōquos" (, "human being, person"). Here "a", being primarily of grid class V, is being used as "an-" and could be used for "al", "am", "ar", and so on.
