What does 착 mean when prefixed to a word?

  • 발신정지 mean stop outgoing calls (on a mobile phone)
  • 착발신정지 means stop both outgoing and incoming calls

Exactly how does 착 function in this case? Are there any other examples of when 착 can be used like this?

  • Note: “발신 정지” and “착·발신 정지” are the recommended spacing and punctuation. This kind of word fusion is common in CJK. Commented Oct 12, 2018 at 16:37

착신 means incoming call, 발신 means outgoing call, and 착발신 is a combination of the two words.

착 is not actually a prefix in this case. It is a Chinese character that means to attach. Therefore, if 신 (signal) is attached (to a phone), it could mean incoming call.

  • 착신 doesn't mean incoming.

  • @Rathony: "incoming" was not a perfect definition, but google translate was close enough to confirm my hunch about how the word was formed and answered my own question. I did not know you were expecting a response to your comment. I already upvoted your answer, which adds a lot of useful information. If you had worded your answer to actually answer the question asked, I would have also accepted it.

  • @Rathony: not at all. Also if you edit your answer, I can still change it to the accepted answer.

'착' is in Hanja which has many meanings. The most important meanings are (1) to attach, (2) to wear, (3) to begin, etc. There are many words that start with this block.

착신: (Mail) arrival of the post or mail, (Telegraph) the receipt (of a message, a telegram)

착륙하다: To land 이륙하다: To take off.

착수하다: To begin (something)

착의(복)하다: To wear clothes (or something)

착용하다: To wear, etc.

You need to note that 착신 doesn't mean incoming. It literally means '착' = to attach + '신' = signal. In other words, literally attachment (receiving) of signal.
