In our modern English Alphabet each letter represents a sound. Each letter in Ancient alphabets represented much more, pictograph (picture), syllable (name), mnemonic (meaning) and phonetic (sound). This unique relationship between the characteristics of the Hebrew letters are used to assist in reconstructing the original Hebrew alphabet and in turn will assist in root and word definitions and relationships.
Each letter is a picture representing something concrete. The Ancient Hebrew pictograph represents a mouth.
The mnemonic meaning of a pictograph is the extended meanings related to the pictograph. For example, the pictograph has the extended mnemonic meanings of speak, blow and open. These mnemonic meanings most often are related to the pictograph by their function rather than appearance.
Each pictograph is associated with a single syllable of two consonants. This syllable is also the name of the pictograph. The name of the pictograph is "peh" and is also the Hebrew word for "mouth."
The first letter of the syllabic name provides a singular sound for the purpose of forming words and sentences. The phonetic value of the pictograph is "p."
