Three consonants carry one idea: moving about for pleasure, a walk, a hike, a trip. The verb is the everyday Israeli word for going on an outing, and the family stays right there: the verb to stroll, the noun for the outing itself, and the seafront promenade where everyone does it. The same root letters also live in טִיל, a missile, something that travels through the air, but the strolling family below is its own friendly cluster. Every word 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.
This root lives in pi'el alone. The doer is מְטַיֵּל, a hiker or tourist out on a trip, formed the regular pi'el participle way even though it is not in the verified family list below. The other binyanim are not lexicalized for this sense.
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.
