The Japanese suffix '毎 (ごと)' is used to indicate 'every' or 'each' in relation to time, frequency, or repetition. It is commonly attached to nouns to express regularity or intervals. For example: every day「毎日」(まいにち), every year「毎年」(まいとし), every time「毎回」(まいかい). This suffix is versatile and can be used with various time-related nouns to convey the idea of something happening consistently or repeatedly. Note that '毎' is often written in kanji but pronounced as 'ごと' when used as a suffix.
