인터넷이 안 돼요.

When to use

State this when you cannot access Wi-Fi or mobile data to explain why apps or websites aren't loading.

How it works

This sentence literally means 'The internet is not working'.

• 인터넷이: '인터넷' (internet) + '-이' (subject particle).
• 안 돼요: '안' (not) + '돼요' (polite present tense of '되다', to work/function).

Pronunciation

Although spelled with a final 'ㅅ', the loanword '인터넷' is commonly pronounced with a 'ㅌ' sound when followed by a vowel, reflecting its English origin. Thus, '인터넷이' sounds like '인터네티' (inteoneti).

Speech Level

The '-아요/어요' ending makes this standard polite speech (해요체, haeyoche). It is appropriate for informing staff, colleagues, or acquaintances about the issue.

Notes

State that the internet connection is not working.
