D-K-Y is cleanness before it is a doctrine: a rinsed cup, skin free of disease, water you can see through. The glossary's curated sense holds the whole range: pure, free of defilement, whether of body, vessel, or heart; the state of being cleansed and fit, the opposite of stained or unclean. Start with the physical and the Beatitude stays honest: pure in heart is not a mood of niceness, it is a heart with nothing smeared across it.
What the Gospels do with this root is move it inward without ever letting go of the concrete. The same word washes a leper's skin, the inside of a Pharisee's cup, and the students at the supper table. This family also carries Palestinian Aramaic (DJPA) attestation: the Galilean-closest evidence for this word.

The inside-out logic of the root is sharpest in Matthew 23:26 ("Blind Pharisee! First clean the inside of the cup, and the outside will be clean too") and in Luke 11:41, where mercy given from within means "everything will be clean for you."
Wash your hands slowly once today, paying attention the whole time. Feel the difference between rinsing something for show and getting it actually clean. Then sit for a minute and ask the same question of the heart (the deciding center, not the emotions): what is smeared across it right now? Resentment, an image you're managing, a corner you cut? Don't scrub. Just see it clearly, the way you'd see a spot on a glass held up to light. Naming it is most of the washing.
The Hebrew cognate family is zakh / zakhah (זַךְ, זָכָה), "pure, clear," with the regular sound shift where Aramaic d answers Hebrew z (Aramaic dhav, Hebrew zahav, "gold"). The same shift links this root to its sister Z-K-Y (day 68), being in the right, prevailing: cleanness turned juridical. And the Beatitude itself welds this root to L-B-B, the heart, tomorrow's root: pure in heart is D-K-Y and L-B-B in one breath. No genuine English descendants.
Spend two or three minutes telling a friend about the three stems of this root (be clean, make clean, be made clean) using the leper of Matthew 8:3 as your example. End with why "You are already clean because of the word" might be the most surprising sentence in the family.
