What it does
Munach Legarmeih is visually a Munach (the usual conjunctive) followed by a vertical bar called Paseq (׀). The bar transforms the Munach into a disjunctive, it stops the flow that Munach would normally continue. Despite the deceptive shape, this is a pause, not a servant.
Where it appears
Less common. Most often seen in verses with complex internal structure, including the priestly blessing (Birkat Kohanim), where Munach Legarmeih separates the three blessings.
How to remember it
Legarmeih means "by itself" or "on its own." The Munach + Paseq together stand alone, separated from the words that follow. The vertical Paseq bar is the visual cue: when you see Munach followed by a vertical line, it's a disjunctive.
Example from the Torah
Bereishis 21:14
Munach Legarmeih on אַבְרָהָ֣ם ׀ sets Avraham's name apart from the action that follows. The Paseq bar (׀) after the Munach is what turns the conjunctive into a disjunctive pause — without it, the same mark on the same syllable would just be ordinary Munach leading straight into the next word.
Hear the melody
A synthesized rendering of the melodic shape, not a vocal recording.
Hand signal (simanim)
Often confused with
A plain Munach with no Paseq is the standard conjunctive (leads forward). Munach + Paseq (the vertical bar) is Munach Legarmeih, which pauses.
