Key Observations

Qal dominance (70.7%)

The Qal is the default stem — simple, active, unmarked. It is used for nearly every common verb in its ordinary sense: to go, to come, to see, to hear, to speak (Qal), to eat, to die. Its overwhelming frequency reflects that most verbal action in the OT is narrated straightforwardly.

The Hiphil (11.5%) — called out

The Hiphil is the causative active stem: it takes a simple action and makes someone cause it to happen. Examples:

• יָצָא (Qal) "to go out" → יוֹצִיא (Hiphil) "to bring out, cause to go out"
• מוּת (Qal) "to die" → הֵמִית (Hiphil) "to kill, cause to die"
• יָדַע (Qal) "to know" → הוֹדִיעַ (Hiphil) "to make known, declare"

At 11.5%, the Hiphil's prevalence reflects the OT's strong emphasis on divine and human agency — God bringing out, making known, causing rain to fall, giving victory, etc.

Piel (8.4%)

The Piel carries intensive or factitive nuance: it either intensifies the simple action (שָׁבַר Qal "to break" → שִׁבֵּר Piel "to smash/shatter") or declares someone to be what the Qal describes (קָדַשׁ Qal "to be holy" → קִדֵּשׁ Piel "to sanctify, treat as holy"). The Piel is particularly common in cultic and legal texts.

Niphal (6.1%)

The Niphal functions as the simple passive or reflexive: "to be seen," "to be called," "to be saved." Its relatively modest frequency compared to the Hiphil and Piel reflects that Hebrew prefers active constructions.

Passive stems (Pual, Hophal — combined 1.4%)

The Pual (passive of Piel) and Hophal (passive of Hiphil) are rare. Hebrew generally avoids double-marking passives; the Niphal handles most passive needs.
