Three consonants carry one idea: going. The verb is the most basic motion in the language, to put one foot in front of the other. But Hebrew lets that simple step radiate outward: the way you walk becomes your gait, the way a process unfolds becomes its course, and the way one is supposed to go becomes the law itself. That last move is the key to the whole family: הֲלָכָה, Jewish law, literally means "the way one goes". Every word below is the same step seen at a different scale. All forms are 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.
לָלֶכֶת is irregular: the root's ה drops out in the infinitive and the conjugation behaves almost like a פ"י verb, which is why it doesn't look like a clean three-letter root. The other binyanim (nif'al, hif'il, hitpa'el…) are not lexicalized for everyday speech, so the work of this root is done mostly through its rich crop of nouns below rather than through many verbs.
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.
