How it's used
Cantonese speakers often drop the number one when it precedes a measure word, especially in casual speech. For example, saying 碗飯 instead of 一碗飯 is perfectly natural and common. When used for emphasis, however, it remains essential to clarify that you mean exactly one and nothing more.

Common mistake
Learners often mistakenly use 一 before every measure word, which can sound slightly formal or robotic. In natural speech, if the context is clear, omitting the number makes your sentences sound much more native.
