The 8 Bridge Types in Chainle: A Working Classification

Almost every Chainle bridge falls into one of eight recognisable types — naming the type turns guessing into classification.

Why classify bridges at all

A Chainle bridge is the route from the clues to the answer. The official journal traces featured answers along specific routes, and the first four types below come from those routes, each anchored to an official worked example. Types 5–8 are this guide’s extension — the same idea applied more broadly so that nearly every bridge you meet has a name and a search strategy.

1. Shared material (shared-material)

Definition: the clues are made of, or filled with, the same substance. Examples: candle + honeycomb → wax (official); a bird and a pillow joined by down (official). How to spot it: ask what the clues are physically made of. When it fails: the shared substance is so broad it turns into a category word, which the specificity adjustment trims in bridge rounds.

2. Part or function (part-or-function)

Definition: the answer is a part of both clues, or plays the same role in both. Examples: faucet + trumpet → valve (official); tree + book → leaf — a part of a tree and a “leaf” (page) of a book (official). How to spot it: ask whether there is a component or role both things have. When it fails: the part is generic — a “base” or “end” of too many things — and the connection goes vague on one clue.

3. Second meaning (second-meaning)

Definition: the answer means one thing in each clue’s context — a double meaning. Examples: piano + lock → key (official). How to spot it: the clues seem unrelated until you find the word that lives in both worlds. When it fails: the two senses are too distant, one clue’s sense links weakly, and the geometric mean drags the score down.

4. Familiar phrase (familiar-phrase)

Definition: the answer completes a common compound or set phrase with each clue. Examples: snow + tennis → ball — “snowball”, “tennis ball” (official). How to spot it: say each clue aloud and listen for the word that naturally follows or precedes it. When it fails: the compound exists with one clue but is a stretch with the other.

5. Shared property (shared-property) — this guide’s extension

Definition: the clues share an abstract quality rather than a thing. Illustrative example: lemon and vinegar both point toward sour. How to spot it: ask what single adjective or quality describes both clues. When it fails: the property is a broad evaluation such as “good”, which the 0.6 adjustment trims.

6. Shared location (shared-location) — this guide’s extension

Definition: the answer is what the clues have in common by place or setting. Example: beach + hourglass + desert → sand (official) — sand is where all three are found. How to spot it: ask where all of the clues happen or can be found. When it fails: the setting is generic (“place”, “world”) rather than specific enough to link strongly.

7. Shared action (shared-action) — this guide’s extension

Definition: the same action applies to both clues. Illustrative example: scissors and grass both invite cut. How to spot it: ask what you do with, or to, both clues. When it fails: the verb fits one clue naturally and the other only metaphorically, leaving a weak link.

8. Shared association (shared-association) — this guide’s extension

Definition: the clues point to the same occasion, culture or idea without sharing a part, place or action. Illustrative example: cake and candles both point toward birthday. How to spot it: ask what occasion, event or idea both clues evoke. When it fails: the association is personal rather than broadly shared, so one link scores well and the other barely registers.

Using the taxonomy

Run the types in rough order of concreteness: shared-material and part-or-function are the most physical; second-meaning and familiar-phrase need lateral thinking; the shared-* extensions cover what remains. Testing candidates against every clue — the decision tree’s core step — matters more than the label you picked.
