M
Name: Muin - upper back, neck; trick, wile, ruse; love, desire, esteem
Pronunciation: mwin
Welsh: mwn - neck, throat
Root: IE: *mono- or *moni-, neck, throat; cognate with L monile - neck, throat
Color: mbracht - variegated [many-colored]
Tree: vine
Bird: mintan - titmouse
MM: tressam fedmae: strongest of powers i.e. the desire or affection for another, strongest of effort, strongest in exertion
MO: árusc n-airlig: condition of slaughter, proverb of slaughter
CC: conar gotha: path of the voice
Other Word Ogams exist for this letter: back of an ox, desire or affection of man
Deities: Ogma as Cermait the Honey-Tongued, Oengus Mac Ind Óg as the God of Love
Meanings: work, effort, carrying a heavy burden, falsehoods, tricks, lies, denial, concealment of facts or truth, love, respect, desire, speaking, communication, riddles, persuasion, flattery
Notes: This word is actually three distinct homonyms in Old Irish, which result in the three groups of meanings seen here. It is my feeling that all three are valid and useful when dealing with interpreting this fid in divination or for use in spiritual or magical work. Its range of meaning makes it quite flexible and useful, and the main meaning in a divinatory context will generally be hinted at by other fiodh in a reading, or by the intuition of the reader. The word ogams suggest all three meanings. The strongest thing in exertion or effort is one's back, and love is among the strongest of emotions. Lies and tricks are conditions which give rise to slaughter. The path of the voice is the throat.

G
Name: Gort - field, garden
Pronunciation: gohrd
Welsh: garth - garden
Root: IE *gher-, *ghort-, to enclose, enclosure, cognate with L hortus - garden
Color: gorm - blue
Tree: ivy, vine
Bird: géis - swan
MM: milsiu féraib: sweeter than grasses, sweetest grass
MO: inded erc: suitable place for cows
CC: sásad ile: sating of multitudes, satisfaction of multitudes
Other Word Ogams exist for this letter: glaisem gelta: greenest of pastures, med n-ercc: counterpart of heaven
Deities: Danu as Land Goddess, Fódla, Banbha and Ériu as eponymous Goddesses of Ireland, Bres as the revealer of the proper times to till, plant, and harvest
Meanings: growth, fertility, plenty, wealth, abundance, generosity, happiness, patience, waiting for fruition, cycles and cyclic time, sanctuary or a place of safety and peace
Notes: The word ogams all support field or garden as the main meaning, and from there all the other potential meanings can arise. Because a garden is often an enclosure of sorts, it can lead to the idea of a sanctuary or peaceful place. Gardening also implies patience and waiting for the proper time of harvest. Having plenty allows for generosity. Abundance and the ability to be generous are often conditions of happiness.

Ng
Name: n-Gétal - killing, slaying, wounding; Cétal - chant, sung or spoken charm
Pronunciation: NYAY-tuhl, KAY-tuhl
Welsh: gwanu - to pierce or stab
Root: IE: gwhen-, to pierce, strike; OI: gonid - wounds, slays; OI: céadal, singing, a song; IE; *kan-, chant, enchant, charm
Color: nglas - green
Tree: broom
Bird: ngéigh - goose
MM: lúth lego: a physician's strength, sustenance of a leech, physician's cry
MO: étiud midach: robe of physicians, raiment of physicians
CC: tosach n-échto: beginning of murder; beginning of slaying
Deities: Dian Cécht the Physician, Miach the Surgeon, the Mórrigan as Battle Goddess
Meanings: wounding, death, healing, beneficial magic, healers, doctors, good health, well-being, hope, regeneration
Notes: Two of the word ogams for this fid point directly to healers and healing as a primary meaning. It should be pointed out that without a wound or an illness, there is no need for healing or physicians, and so a wound would be a necessary precondition to a healing. The second meaning of cétal, a chant or charm, is suggested by Meroney rather than McManus, but makes sense in the context of the word ogams, and also appears to have roots that directly express the majority of the word ogams, so I prefer this reading. Dian Cécht was invoked in oral charms for healing and aid, and charms both oral and physical were frequently used as part of healing practices. I generally see this fid as indicative of healing unless it is near h-úath or ruis, in which case its damaging tendencies would more likely manifest.

Sr
Name: Sraiph - sulfur
Pronunciation:srayf (roll the r a bit)
Color: sorcha - bright
Tree: sloe (blackthorn), willowbrake
Bird: stmólach - thrush
MM: tressam rúamnai: strongest of red, strongest reddening dye
MO: mórad rún: increasing of secrets, increase of secrets
CC: saigid nél: seeking of clouds i.e. its smoke above it
Deities: Senchán Torpéist, Fionn mac Cumhaill as Seer
Meanings: transformation, transcendence, spiritual work, secrets, magical or occult mysteries, shapeshifting, divination, taking of omens
Notes: This fid's meanings bring to mind aspects of classical alchemy and alchemical transformation. Sulfur is a major part of many alchemical processes. The dying referred to here is spoken of in the texts as dying white gold to red through a process involving the use of urine (ammonia). "Increase of secrets" may refer to the counterfeiting properties of disguising one metal as another by alchemists seeking to turn "base metal" into gold. In all, my feeling is that sulfur implies transformations and spiritual work (if one at least tentatively accepts a more Jungian view of alchemy), and that transformation leads to the concept of shapeshifting, which is yet another type of transformation. This can be spiritual shapeshifting, changes in one's personal life, or physical transformations of one sort or another. In ways, I see this as having a similar function to the Death card in the tarot; one transforms by leaving the old behind as the caterpillar leaves the chrysalis as a butterfly.
   The word ogam "seeking of clouds" seems to refer specifically to the divinatory and omen taking technique called néldoracht. Some would interpret that art as "astrology" but gazing for shapes in clouds is a common enough activity that it would seem to be ripe for use in omen taking. It could also refer to the smoke of burning sulfur.
   The "deific" figures chosen to represent this fid are not "divine" per se. Senchán Torpéist was a Fili who did historically exist, but his legend grew to such an extent that he is credited with feats that seem quite supernatural. He is best known for his "recovery" of the Táin Bó Cuailgne, which he was said to have heard from the spirit of Fergus Mac Róich himself, while seeking visions on a sídhe mound. Fionn mac Cumhaill is one of the preeminent Filidh of Scottish and Irish mythology. Both are well known for their ability to pierce the deepest mysteries.

R
Name: Ruis - redness
Pronunciation: roosh
Root: OI: ruise, red; IE: *reudh-, red
Color: ruadh - red-haired
Tree: elder, bog berry(?), fern
Bird: rócnat - rook
MM: tindem rucci: most painful of shames, intensest of blushes, most intense blushing
MO: rúamnae drech: redness of faces, reddening of faces
CC: bruth fergae: glow of anger
Deities: Cú Chulainn as the Hound of Ulster, Fergus mac Róich
Meanings: shame, anger, embarrassment, guilt, jealousy, warrior's frenzy, loss of control, obsession, sexuality and eroticism or their abuse, ecstatic trance
Notes: Redness in the mythology can refer to many different things, and so can be tricky to interpret. It is a sign not just of anger or shame, but also of the warrior in frenzy, the color of blood and visions, and the flush of sexuality. Lips and cheeks of the beautiful and beloved are red. Vision-causing berries are red or crimson, as are the hazels of wisdom. Though they are described in some texts as "purple" it should be noted that at the time, "purple" was more of a dark, blood red if we look at the dyes used then.
    Cú Chulainn is famous for his warrior frenzy or "ferg" (which translates as anger) which manifested as a warping or twisting, and grotesque physical changes in the stories about him. Fergus mac Róich, Cú Chulainn's warrior-mentor, also manifested the ferg. Fergus is also associated with sexuality. The name Róich may be derived from a name meaning "great horse." He was said to have immense genitals and require seven women to satisfy him.
