Picture one act: hanging something on a hook. From that physical image Hebrew draws an abstract chain. A thing that hangs on a wall becomes a matter that hangs on a condition, that is, depends on it; an issue left hanging is unresolved. So the same root gives "to hang (a coat)", "dependent", and "dependence". The third letter ה is weak (a ל"ה root), so it drops in the verb. Every 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.
The pa'al litlot is the active act of hanging; the nif'al lehitalot is its passive partner, "to be hung". The pi'el, hif'il and hitpa'el are not lexicalized for this root in everyday Hebrew, so the dependence sense lives in the nouns and adjective rather than in a dedicated verb.
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.
