The Japanese suffix '秒 (びょう)' means 'second' and is used as a unit of time. It is commonly attached to numbers to indicate a specific number of seconds. For example: 10 seconds「10秒」(じゅうびょう). It can also be used in expressions like 'a few seconds'「数秒」(すうびょう). This suffix is essential for discussing time durations in Japanese, whether in everyday conversation or technical contexts. Note that '秒' is always used as a suffix and never stands alone as a word.
