Inseparable Prepositions & the Vav Conjunction

Biblical Hebrew has four one-letter prepositions that never stand alone — they glue onto the next word. The most flexible of these is וְ (wə, "and"), which has more faces than a classroom full of students. This article teaches the prepositions בְּ, לְ, כְּ, מִן and the many forms of וְ.

The four inseparable prepositions

Vowel changes

When attached to a word, the vowel of the preposition can change depending on the first letter or the stress of the following word:

וְ — "and" and much more

The conjunction וְ (wə, "and") is the most common word in the Hebrew Bible. It is usually attached to the next word as a prefix.

Basic form: וְ

Before most consonants:

וַ — the vav consecutive (common in narrative)

Before an imperfect verb, וְ often becomes וַ (wa) and causes dagesh forte in the next letter. This is the famous vav-consecutive that drives biblical narrative:

💡 Tip: וַ + yod imperfect = וַיִּ... (way-yi...). וַ + tav imperfect = וַתִּ... (wat-ti...). The doubling of the prefix consonant is the tell-tale sign.

ו before labials

Before the labial consonants ב, מ, פ, the vav becomes a shuruq (וּ):

ו before shewa

Before consonants with shewa, ו often becomes וּ (û):

Prepositions with pronominal suffixes

The inseparable prepositions can take pronoun suffixes directly:

These suffixes are worth learning gradually; they appear on almost every page of the Bible.

✅ Key takeaways

• The inseparable prepositions are בְּ, לְ, כְּ, מִן.
• They attach to the next word and change vowels before gutturals, ר, or the article.
• וְ ("and") is a prefix with many forms: וְ, וַ, וּ.
• וַ + imperfect verb = vav-consecutive narrative ("and he/she/they...").
• All four prepositions can carry pronominal suffixes.
