- Armeria maritima — Scientific name for a popular species of perennial herbaceous plant in the Plumbaginaceae family, commonly known as thrift, sea thrift, or sea pink. This highly salinity-tolerant structural plant is native to maritime coasts across the Northern Hemisphere, forming compact grass-like tufts with erect stems bearing pink, white, or purple globose inflorescences, widely used as a border and rock garden ornamental.
- Armorica — Ancient historical and geographical name used during the Gallo-Roman period to designate the coastal region of Gaul between the Loire and Seine rivers, directly including modern Brittany. The name originates from Gallic meaning 'the place by the sea'.

- Foreshore — A sector or strip of the coastal zone located at the boundary between land and sea, extending between the high-water mark during high tide (flood) and the low-water mark during low tide (ebb); the active swash zone. In an extended geological sense, the term can also describe a shallow submerged sandbar extending from the beach face toward the open sea, where incoming waves break continuously.
- Backshore — The part of the beach lying between the berm crest and the coastline, cliff, or sand dunes, located above the mean high-water line of normal tides. This structural sector is submerged exclusively during exceptional storms or extraordinary spring tides, being characterized by dry sand accumulations and specific salinity-resistant coastal vegetation.
