The connective ending -아/어서인지 is used to express a speculated or uncertain reason for a particular situation or outcome. It combines the reason-giving ending -아/어서 with -인지, which conveys a sense of questioning or uncertainty. Essentially, the speaker is offering a plausible explanation but is not entirely sure if it's the definitive cause.
Use -아/어서인지 when you are observing a situation and trying to hypothesize the reason behind it. The speaker is not stating a definite cause, but rather suggesting a possible one. It's often used when you see a result and are trying to figure out why it happened, implying a degree of doubt or conjecture. This expression is suitable for situations where you want to convey that "it seems like this is the reason, but I can't be 100% certain."
This expression attaches to the stem of verbs and adjectives after the -아/어서 form.
