Memory Aids
Mnemonic
Think of the Christian 'Trinity' (three-in-one) and a 'House' as a governing body. Trinity House is the one unified authority for three key things: lighthouses, buoys, and pilots.
Conceptual Metaphor
INSTITUTION IS A BUILDING / GUARDIAN: The 'House' metaphor establishes it as a permanent, solid, governing body. It is conceptualized as a guardian or warden of the seas.
