Three consonants hold one act: hearing. This is the root of the Shema, Judaism's central call to listen. Follow it through the binyanim and you watch one ear-event split into roles: you hear, something is heard (and so is obeyed), or you make a sound for others to hear. Then the nouns take the next step: what is heard becomes meaning, and a heard command becomes discipline. Each word here is verified against pealim, niqqud included.
The same root runs through the verb system. Each binyan is a voice: it bends the one idea into active, passive, causative or reciprocal. Tap to hear.
Notice the elegant split: pa'al is the plain act (I hear), nif'al is the passive that drifts into "to obey" (what is heard must be heeded), and hif'il is causative (make others hear, hence play music). The pi'el, pu'al and huf'al are not lexicalized for this root.
Same root letters, different noun moulds (mishkalim). The mould tells you the function: who does it, the act of doing it, or the thing produced.
Strip the prefixes, suffixes and vowels. Three consonants remain, and the meaning lives there.
