The Nuance Difference: "毎年" vs "しつれいします"

In Japanese, both 毎年 and しつれいします are often translated to English but have distinct usages. 毎年 (まいとし (maitoshi)) represents "every year" (Level: N5) and typically represents Indicates an action or event that occurs yearly. 「毎年」 can also be read 'mainen', but 'maitoshi' is more common in N5 level spoken Japanese.. On the other hand, しつれいします (しつれいします (shitsurei shimasu)) translates to "Excuse me; Sorry to bother you; Goodbye (when leaving someone's office/home)" (Level: N5) and is used for Literally 'I'm committing a rudeness.' Used when entering/leaving a room, interrupting someone, or asking to pass by. It's a polite apology for a potential inconvenience.. Mixing these up can sound unnatural to native Japanese speakers!
