Three consonants carry one idea: being alive. The same letters give you the verb to live, the adjective alive, the noun life itself, and a whole chain of words about vitality, revival, and what keeps a person going. The third letter ה is weak, so it bends in the vowels, but the meaning never moves. None of these words is memorized separately. They are the same root seen from different angles. 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.
Three binyanim are lexicalized, and they line up neatly: pa'al is simply to live, hif'il is causative, to make live again, to revive. The passive partners nif'al, pu'al and huf'al are not lexicalized for this root, and there is no everyday hitpa'el. That is normal: not every root fills all seven moulds.
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.
