結構{けっこう}と決行{けっこう}と欠航{けっこう}


I'm sure the YouTuber Dogen's name would not be strange to a lot of people
here on this site, and I'm sure a lot of you have seen his [this
video](https://www.youtube.com/watch?v=J2vVPpbEdH0) where he makes fun of
words that sounds similar.

Specifically, if you watch the first minute of the video, you can see he makes
a skit from the word 決行{けっこう} and 欠航{けっこう}, which mean completely opposite
things in that context of a ferry ride.

My question is: is what he's showing a possible real-life situation? If not,
why? Can people ever mishear 結構{けっこう} and 決行{けっこう} and 欠航{けっこう} since they
could all make sense in the same context?

P.S. I know the pitch accent is slightly different but is that the only
distinction between these words when spoken? Do you have to like draw kanji in
the air to convey the right word sometimes?




I haven't watched the whole video, but it is unlikely to happen.

  * 結構です sounds rather distinctly from 欠航/決行です
  * In the context of talking about the ship's operation, 平常運行です/{平常通り,予定通り}運行します will be used instead of 決行する, to mean that they function normally.
  * 決行, as explained in the related question in the comment, is used about events. The most timely example would be パンデミックにもかかわらずオリンピックは決行された : _The Olympics were held in spite of the pandemic_ :)

Apart from 欠航/結構/決行, we rarely have such comedies of errors in reality. When
we sense something is wrong in the conversation, we just confirm with each
other.

There is a famous [comedian
duo](https://ja.wikipedia.org/wiki/%E3%82%A2%E3%83%B3%E3%82%B8%E3%83%A3%E3%83%83%E3%82%B7%E3%83%A5)
(one of them became quite notorious due to some affairs...) that make lots of
comedies of that type. I found [this](https://lion-news.tokyo/archives/13010),
where the same type of (supposedly real) conversations are collected from
twitter. (Not all of them are about 同音異義語, but several. E.g. 7 in the link
gives a conversation where 声優 (voice actor) and 西友 (a supermarket) are
confused).
