Frequentemente confundido com
Riyou often implies using a service or using something to one's advantage, while Shiyou is more about the mechanical act of using a tool.
Tsukau is the general, native Japanese verb for 'to use', whereas Shiyou is the formal, Sino-Japanese noun/verb used in writing and signs.
Notas de uso
Shiyou is more formal than 'tsukau' and is the standard word used in manuals and on public notices. It is usually combined with 'suru' to function as a verb.
Erros comuns
Learners sometimes use 'Shiyou' when talking about using people (hiring or directing them); 'Tsukau' or 'Yatou' is more appropriate as 'Shiyou' makes people sound like inanimate objects.
