A comb and the teeth riddle: read the feature by its use
A comb answers "What has many teeth but cannot bite?" Its teeth pass through hair rather than bite. The path to the solution is to separate the name of a feature from the action that the question places beside it. "Many teeth" tells us what the answer has. "Cannot bite" tells us which action those teeth do not perform. Both clues remain useful when read together. The explanation supplies the missing function, passing through hair, so the answer fits the feature without needing to fit the action that the question excludes.
Begin with the wording rather than a list of possible objects. Separate the positive clue from the limiting clue, then ask what each requires. Keep both requirements visible while considering a candidate. A useful answer needs to account for the whole question, including the small words that join its parts. Read slowly enough to notice whether a word names an action, a feature, or a relationship. This gives the search a clear direction without requiring a guess at the start. The aim is to find an interpretation that lets the clues work together, then explain that interpretation in ordinary language.
A comb meets the positive clue through its teeth and the limiting clue through their use. Take the word "teeth" as the point to examine, then ask whether every feature with that name must perform the same action. The answer gives a specific alternative within the puzzle: passing through hair. That connection is enough to reconcile the clauses. The solution is therefore about the meaning of a named feature in context. It does not need extra details about appearance or materials. Keep attention on what the teeth do, because that is the explanation supplied for why biting does not fit.
Next, test the candidate by placing it back into the question. Read the complete sentence with that answer in mind and explain each clause separately. If an explanation leaves part of the wording unused, return to that part before settling on a solution. Avoid adding extra conditions just to make a candidate fit. Instead, look for the smallest change in interpretation that accounts for the contrast already present. This method keeps the reasoning tied to the puzzle and makes the final explanation easier to follow. It also gives a way to inspect a promising answer without needing a long list of alternatives.
A comb gives a clean way to check the candidate against the whole sentence. First, retain "many teeth" as the identifying clue. Next, connect those teeth to passing through hair. Finally, compare that function with biting, the action ruled out in the question. This sequence uses every part of the wording without adding a separate scenario. The useful shift is from asking what usually comes to mind beside "teeth" to asking what the named feature does in this answer. The latter question leads directly to the given explanation and keeps the solution grounded in the riddle.
For another puzzle of this kind, make a short working note with the clue on one side and its possible interpretation on the other. Treat an early idea as a candidate to test. Ask whether a key word could refer to something other than the sense first considered, or whether the action depends on what it acts upon. Keep the question intact while exploring those possibilities. The best next step is a precise question about the wording, such as what the verb describes or what a named feature does. That approach turns an open search into a series of manageable reading decisions.
A comb resolves the contrast by giving the teeth a function other than biting. When approaching another feature riddle, keep the noun available while examining its relationship to the verb. A shared feature name need not force the action suggested beside it. Here, the explanation makes that distinction explicit by describing the teeth passing through hair. The answer and the reasoning can then be stated together without extra embellishment. Read the final sentence as a check: the candidate has the named feature, the feature performs the supplied function, and the limiting clue remains satisfied throughout the explanation.
Finish by stating the answer and the connection that makes it fit. Aim for an explanation short enough to check against the question without losing any essential part. Then read the question once more, now with the solution in place. Notice which word or relationship carried the puzzle and which detail confirmed the answer. There is no need to rush this final pass; it is the part that makes the solution feel settled. For future riddles, keep the same habit: separate the clues, explore the relevant meanings, test a candidate against every clause, and explain the fit in a clear sentence.
