י־ב־ל is an old root about flowing and bringing forward. A יוּבַל is a stream; the Jubilee (יוֹבֵל) was a year ushered in by a ram's horn. In modern Hebrew the dominant senses are to lead / to transport (to bring something along) and produce / yield (what the soil brings forth). The first letter is a weak yod that disappears in the hif'il, surfacing as a long o: לְהוֹבִיל. Watch one image, carrying forward, turn into a leader, a moving van, and a field's crop. 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 everyday verb is the hif'il לְהוֹבִיל: causative "to bring forward", hence both to lead and to transport. Note how the weak yod of the root vanishes and reappears as the long o (הוֹ-) typical of פ"י (first-yod) roots in the hif'il. The pi'el לְיַבֵּל (to cause corns) is a marginal, specialized sense. No pa'al, nif'al, pu'al, huf'al or hitpa'el are lexicalized for this root today.
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.
