clew line
Very Low (C2+)Technical/Maritime/Historical
Definition
Meaning
A nautical rope attached to the lower corners (clews) of a sail, used for raising or tightening it.
A term from traditional sailing vessels referring specifically to lines that control the sail's bottom edge. In modern figurative use (rare), it can refer to any guiding or controlling line in a complex system.
Linguistics
Semantic Notes
This is a highly specialized term used almost exclusively in the context of square-rigged sailing ships. It is a compound noun where 'clew' refers to the lower corner of a sail, and 'line' is nautical terminology for a rope with a specific function. The term is frozen and not productive in modern general English.

Connotations
Evokes historical sailing, traditional seamanship, and nautical heritage equally in both varieties.
Frequency
Extremely rare in general use. Frequency is identical and confined to nautical contexts, historical fiction, and maritime museums/manuals.

Learning
Memory Aids
Mnemonic
Think: To get a CLUE about the sail, look at its bottom corners (CLEWs), controlled by the CLEW LINE.
Conceptual Metaphor
CONTROL IS HOLDING THE LINE. The clew line is the means of controlling a specific part of a larger system (the sail).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'линия подсказки' (clue line). 'Clew' here is not related to 'clue' (подсказка). The closest would be 'нирал' or specific 'шкот/фал/брас' depending on exact function and sail type.
Common Mistakes
- Misspelling as 'clue line'.
- Using it as a general term for any rope on a boat.
- Confusing it with 'sheet' (which controls a sail's angle, not primarily its clew height).

FAQ
Frequently Asked Questions
No. On a square-rigged ship, a sheet controls the sail's angle to the wind from the clew. A clew line specifically hauls the clew up towards the yardarm to gather or furl the sail.
Almost certainly not, unless you are actively discussing the rigging of traditional sailing ships. It is a highly technical, historical term.
They are different words with different origins. 'Clew' in sailing comes from Old English 'cliwen' meaning a ball of yarn or thread,引申为 the corner of a sail to which lines are attached. 'Clue' (meaning a hint) is a later variant spelling of 'clew', from the idea of using a ball of thread as a guide (like in the Minotaur's labyrinth).
Generally, no. Modern fore-and-aft rigged yachts use 'sheets' and 'halyards'. 'Clew line' is specific to the square-rigged sailing ships of the past.
