This root holds two faces of one act: to uncover. Lift the veil off a thing and you reveal it; lift a people off their land and you send them into exile. Hebrew kept both meanings in the same three letters, so revelation (גִּלּוּי) and exile (גָּלוּת) are cousins. The pa'al carries the exile sense, the pi'el carries the discovery sense, and the nouns fan out from there. 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.
One root, two binyanim, two destinies. The pa'al לִגְלוֹת drifted toward the painful sense (to be uncovered from your land = exiled), while the pi'el לְגַלּוֹת took the active, hopeful sense (to uncover a truth = to discover). The other binyanim are not lexicalized for everyday Modern Hebrew.
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.
