Muin is the eleventh letter of the ogham alphabet, written ᚋ, and in the Celtic tree calendar it is linked to the vine. It carries themes of insight, introspection, and release. One honest note first: the grapevine is not native to Ireland or Britain, so the vine reading is a later interpretation rather than firm ancient lore. For the whole alphabet see the ogham letters guide, and for every symbol at a glance, the ogham symbols page.
The letter Muin
Muin is the first few of the third group, or aicme, written as a single stroke crossing the central line at an angle: ᚋ. Its sound is M. In the traditional order it opens the third group, before Gort.
The vine in tradition
Because grapes were imported rather than grown in the Celtic north, the vine’s place in ogham owes more to the later tree calendar than to native Irish tradition, and some readers link Muin instead to the bramble or blackberry, which does grow wild there. Either way, the associations that gathered around the letter come from the vine and its fruit: the harvest, the making of wine, and the loosening of the tongue and the mind that wine brings. From there Muin took on ideas of prophecy, honest speech, and looking inward.
What Muin means in ogham
In modern ogham practice, Muin is read as insight, introspection, and release, a sign to look honestly within and to let something go. Because the vine reading is itself a later one, this meaning is best treated as a modern interpretation, which is generally true of the divinatory meanings but worth stressing here. See the ogham symbols and their meanings page for the full set.
Vine in the Celtic tree calendar
Vine is one of the signs in the Celtic tree calendar, covering roughly September 2 to September 29, around the grape harvest. That calendar is a modern creation, traced to Robert Graves in 1948 rather than to ancient astrology. If you were born in the vine period, the Celtic tree calendar and find your birth tree guides cover the sign in full.

What plant is Muin?

Is the vine native to Ireland?
