The phrase “hey sis” is an informal and affectionate way of addressing one’s sister. Here are some synonyms that can be used in similar contexts:
“hi sister” is a straightforward alternative. It maintains the informality and warmth. For example, “Hi sister! How are you today?” It’s a simple greeting that conveys a similar level of familiarity.
“yo, sis” has a bit more of a casual and trendy tone. “Yo” is a very laid-back way of getting someone’s attention. For instance, “Yo, sis! Check this out.” It’s a phrase that might be used among younger siblings or in a more relaxed setting.
“hello, sis dear” is a slightly more endearing version. The addition of “dear” makes it a bit more affectionate. For example, “Hello, sis dear! I missed you.” This could be used when you want to express more warmth and love.
