1
person or team trying to take title
A person or team that tries to beat the person or team who is champion or in power now.
用法パターン：
a challenger to [someone/something]
よくある間違い：
Learners sometimes confuse "challenge" and "challenger". "Challenge" is the task or action (for example, "This game is a big challenge"), while "challenger" is the person or team trying to beat someone else (for example, "He is the challenger"). Learners may also say "the challenge to the champion" when they mean "the challenger to the champion".

対義語
incumbent (The person who currently holds a position or office, whom the challenger is trying to replace.)

competing product or organization
A company, product, or idea that tries to be as good as or better than the main one in a market.
用法パターン：
a challenger to [a product/company]
よくある間違い：
Learners sometimes use only "competition" instead of a countable noun like "challenger" or "competitor". In business English, it is natural to say "a strong challenger" or "a new competitor", not just "strong competition" when referring to a specific company or product.
類義語
competitor (Very close in meaning; more general and slightly more common in business contexts.)
|
rival (Similar meaning but can sound slightly more dramatic or emotional.)
対義語
market leader (The company or product with the largest share or strongest position in a market, which challengers compete against.)

person who questions authority or norms
A person who strongly questions or fights against usual ideas, rules, or powerful people.
用法パターン：

類義語
critic (Focuses on someone who points out problems or faults, not always in a competitive context.)
