פַּחַת (pakhat) — pit, deep hole in the ground
Etymology
The word פַּחַת is a biblical Hebrew word for a deep pit or chasm in the ground. It appears in Isaiah 24:18 in the memorable parallel: "מִתּוֹךְ הַפַּחַת יִלָּכֵד בַּפָּח" ("he who escapes from the sound of terror will fall into the pit; he who climbs out of the pit will be caught in the snare"), which gave rise to the modern Hebrew idiom מִן הַפַּח אֶל הַפַּחַת ("from the trap into the pit"), meaning "going from bad to worse." The word also appears in 2 Samuel 18:17 in the context of burying Absalom: "they threw him into a great pit in the forest."
The word's main linguistic interest lies not in its meaning but in its form. פַּחַת is a member of the segolate noun class — a group of nouns with stress on the first syllable (penultimate stress, called mil'el in Hebrew), in contrast to the vast majority of Hebrew words which are stressed on the final syllable (mil'ra). The segolates include familiar words like מֶלֶךְ (king), אֹזֶן (ear), מֶלַח (salt), and סֵפֶר (book). All segolates are nouns; no other Hebrew noun pattern is restricted to a single part of speech in this way.
The segolate pattern is a historical fossil. In Proto-Semitic, nouns had case endings (like Latin and Greek) that changed with grammatical function: nominative, accusative, and genitive. Classical Arabic preserved this system, but it was lost in Hebrew before the biblical texts were written. When case endings dropped off, certain nouns that originally ended in a cluster of two consonants (e.g., *malk-) acquired an "epenthetic" helping vowel between those consonants to make them pronounceable. In most cases this vowel was the segol (e), giving words like *malk > מֶלֶךְ. When the consonant cluster involved a pharyngeal or laryngeal consonant (alef, ayin, het, he), the epenthetic vowel was a patah (a), which explains why פַּחַת (from earlier *pakht-) ends in -ahat rather than -ehet. The original stress on the first syllable was preserved, making these nouns "irregular" in the framework of Modern Hebrew.
The original vowels of segolates are still visible when suffixes are attached. When one says מַלְכִּי ("my king") or מְלָכִים ("kings"), the underlying form *malk- resurfaces, showing that the -e-e- pattern of מֶלֶךְ is secondary. Modern Hebrew has continued creating new segolates: דֶּלֶק (fuel), בֹּרֶג (screw), תֶּפֶר (seam), and רֹטֶב (sauce) all follow the ancient pattern, with first-syllable stress and plural forms like דְּלָקִים and בְּרָגִים that reveal the original consonant cluster.

Timeline
- Proto-Semitic: *pakht- or similar form; case endings still present
- Pre-biblical: case endings lost in Canaanite/early Hebrew; epenthetic patah inserted; stress preserved on first syllable
- Biblical period: פַּחַת attested as "deep pit" in Isaiah and Samuel
- Modern Hebrew: survives in idiom מִן הַפַּח אֶל הַפַּחַת ("from bad to worse")
- Modern Hebrew: segolate pattern continues to be productive for new coinages (דֶּלֶק, בֹּרֶג, etc.)
