The three root letters, coloured inside the word
Shoresh mode colours the three-letter root inside every word it knows, so a child sees what the word IS before what was put around it. Hover a word and a small bubble gives the root and what it means. It is how a Rebbi teaches at the board — find the shoresh — done for every word on the page.
A lexicon, not a guess
A word is coloured only because someone put its root in the lexicon. An algorithm that strips prefixes and suffixes gets one root in twenty wrong — אותנו as “sign”, בשורות as “ox” — and a wrong shoresh looks exactly like a right one on a child’s screen. So it does not run. Coverage grows by review: the dictionary agent proposes, a second reader refutes, and only what survives is written.
Weak roots are still found
הודו is ידה with the י written as ו; תפלה is פלל with the doubled letter shown once. The matcher knows the standard shapes a weak root takes, so it colours the letters that ARE printed and never invents one.
The right letters, not the nearest ones
In ללמד the second ל is the root’s, not the prefix; in מלכותך the כ is the root’s, not the suffix. The placement rule is that the root letters sit together and the grammar wraps around them.
What is left plain, on purpose
Shem Hashem, names, particles, two-letter nouns and Aramaic carry no root and are never coloured. What remains uncoloured beyond that is the lexicon’s next work, and it is measured.
Who it's for — For the child learning to see Hebrew as roots and patterns rather than shapes to memorise, and for the adult who wants the grammar to become visible. Premium and up on the seforim; free inside My Siddur, where tefilah is given away.
One toggle on the reader's toolbar, and it follows you from the Siddur to the Kitzur.
