The everyday verb here, לְקַבֵּל, is one of the first you learn: to receive, to get, to accept. But the root spreads in surprising directions. Kabbalah is literally "that which is received", the received tradition. A thing that "holds and takes in" becomes capacity, a capacitor. To set two things to face and accept each other gives parallel. And the plain pa'al, oddly, means to complain. One root, from a receipt to the divine tradition. 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 headline verb sits in pi'el (לְקַבֵּל), not pa'al, which is unusual; the pa'al here drifted to a separate sense, "to complain". Hitpa'el supplies the passive ("to be accepted"), and hif'il branches off into "to set parallel / to compare". The pu'al and huf'al are not lexicalized.
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.
