Final answer:
The abbreviation for "every morning" is "a.m.," which means "before noon" in Latin and is used to denote activities occurring in the morning.
Step-by-step explanation:
The simple appropriate abbreviation for "every morning" is "a.m." which stands for the Latin term ante meridiem, meaning before noon. This abbreviation is relevant in contexts like discussing daily routines or symptoms that are most common when first arising in the morning. For instance, some people might experience stiffness that improves as they engage in their everyday tasks.
English speakers often use "a.m." to describe an action that occurs in the morning hours, such as "My neighbor walks her dog at 7 a.m." This abbreviation helps to specify the time of day when events take place, distinguishing morning activities from those in the afternoon or evening.
