Morphology

Plimsoll + mark

The phrase is a straightforward combination of the proper name 'Plimsoll' and the noun 'mark' (a symbol), so its meaning is simply the mark called the Plimsoll that indicates a ship's maximum safe draft. Although 'Plimsoll' is a specialized term, if a learner knows both constituents the composition follows a common name+noun pattern and the overall meaning is directly derivable.

Etymology

The Plimsoll mark is a painted mark on a ship's side that shows how high the ship can be loaded. It was named after a man called Samuel Plimsoll who wanted a clear sign so people could see the ship's 'safe limit'. If the water reaches the line, the ship is too heavy.
