T stands for Tinne, or Teine, the Holly tree. This evergreen plant is connected to immortality, unity, courage, and the stability of hearth and home. Pronounced chihnn-uh by the Celts, the wood of the Holly was often used in the construction of weapons, and is known as a plant of warriors and protectors.
In the pre-Christian British Isles, the Holly was often associated with protection -- planting a hedge around your home would keep malevolent spirits out, thanks in no small part to the sharp spikes on the leaves. In Celtic myth, the concept of the Holly King and the Oak King symbolizes the changing of the seasons, and the transition of the earth from the growing time to the dying season.
When Christianity moved into the Celtic lands, the new religion associated the Holly plant with the story of Jesus. The poky spikes on the leaves represent the crown of thorns worn by Jesus on the cross, and the bright red berries symbolize his blood.
