One of the oldest roots in Hebrew braids three things together: the colour red, the human being (adam), and the red earth (adama) from which the human is named. The thread is the reddish-brown soil: the colour gives the gem and the lipstick, the soil gives the ground, and the human is the one made of that ground. Pour the letters into the causative verb mould and you even get "to blush", redness rising in a face. 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.
This root lives mostly as colour and noun, not as a busy verb. Only the hif'il is lexicalized, and it reads as inchoative: to become red. The plain pa'al "to be red" is expressed by the adjective אָדֹם instead, which is why the verb column here is a single row.
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.
