Three consonants carry one idea: to reign. The same root gives you the king and the queen, the kingdom they rule, the act of crowning them, and the abstract quality of statehood. Notice how the political vocabulary of a whole language unfolds from one verb. Hebrew even borrows this root to mean "to advise", because a counsellor is one who helps you reign over a decision. 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.
Only the simple pa'al is lexicalized here as the everyday verb. The system also knows a hif'il "to crown / to make someone king" (לְהַמְלִיךְ) and its action-noun הַמְלָכָה appears below, but the core meaning lives in the plain pa'al "to reign".
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.
