1
person or group that promotes something
A person or group that strongly supports or advertises something so that more people will like, buy, or agree with it.
用法パターン：
[someone] is a promoter of [something]
よくある間違い：
Learners sometimes confuse 'promoter' with 'sponsor'. A sponsor usually gives money or resources to support something, while a promoter mainly advertises or encourages it, and may not always provide funding. Another common mistake is the misspelling *promotor*, which is incorrect in standard English for this meaning.

advocate (Often stresses public speaking or writing in support of a cause, sometimes more formal than 'promoter'.)
|
supporter (Broader and more general; does not always suggest active advertising or marketing.)
|
champion (Emphasizes strong, energetic support, often for a social cause or idea.)
対義語
opponent (An opponent works against an idea or cause instead of helping it succeed.)
|

organizer of shows or sports events
A person or business that organizes and advertises concerts, sports games, club nights, and other events to make money.
用法パターン：
[someone] works as a promoter for [an event / a venue]
よくある間違い：
Learners sometimes mix this meaning with the general sense of 'promoter' as just a supporter. In entertainment news, a 'promoter' is usually a business role responsible for organizing and marketing events, not simply someone who likes or supports the band or sport.
類義語
organizer (General word; does not always include the idea of marketing and taking financial risk.)
|
producer (Common in entertainment; often focuses more on creative control or financing than on advertising and ticket sales.)
対義語
spectator (A spectator only watches the event instead of arranging, financing, or advertising it.)

DNA region that starts transcription
In biology, a short part of DNA where special proteins attach so that the cell can start copying a gene to make RNA.
用法パターン：
[protein] binds to the promoter of [gene]
よくある間違い：
Students sometimes confuse a 'promoter' with an 'enhancer'. A promoter is directly next to the gene and is essential for starting transcription, while an enhancer can be far away and only increases or controls the level of transcription.
類義語
regulatory DNA sequence (A broader technical term; not all regulatory sequences are promoters, but all promoters regulate transcription.)
対義語
coding region (The coding region is the part of a gene that contains the information for a protein, while the promoter controls when transcription starts and does not encode protein.)

person who sets up a company
In business, a person who starts a company and organizes the money, legal papers, and first plans for it.
用法パターン：
[someone] acts as a promoter of [a company]
よくある間違い：
Learners often assume 'promoter' here simply means 'person who advertises a company'. In law and finance, a promoter is specifically the person or group that sets up the company, prepares documents, and arranges early funding, not just someone who markets the business.
類義語
founder (Common everyday word; a founder starts a company but may not cover all the specific legal and financial duties of a 'promoter' in company law.)
|
entrepreneur (Highlights a person who starts new businesses in general, with a focus on risk-taking and innovation rather than formal legal formation.)
対義語
liquidator (A liquidator is responsible for closing down a company and selling its assets, which is the opposite stage of starting and organizing a company as a promoter.)

substance that enhances a catalyst
In chemistry, a material added to a catalyst or process to make it work better, even though it is not the main catalyst.
用法パターン：
[substance] acts as a promoter in [reaction]
よくある間違い：
Learners may think a 'promoter' is the same as a catalyst. In this technical sense, the catalyst is the main substance that speeds up the reaction, while the promoter is an extra substance that helps the catalyst work better.
類義語
activator (A broader technical term; an activator increases reaction rate, while a promoter is specifically used together with a catalyst.)
対義語
inhibitor (An inhibitor slows down or stops a reaction, while a promoter increases the effectiveness of the catalytic process.)
