The classical line "俟我于城隅" means "waits for me at the corner of the city wall".
Tips
history
俟 is essentially classical: modern Chinese says 等待 instead. The line quoted is from the Book of Songs. It is also read 俟 only in the rare compound surname 万俟. Built from the person radical 亻 and 矣.
register
Literary and classical only — appears in old poetry and set phrases like 俟机, not in everyday speech.
矣 on the right supplies the sound frame for the sì reading. It is itself a classical sentence-final particle, fittingly paired here with a classical-only verb.
