it seems like; I heard; apparently~
Expresses hearsay or appearance based on evidence, meaning 'it seems like' or 'I heard'.
らしい is used when you have some evidence or reason to believe something, and it can also report what you have heard. It is often translated as 'seems like' or 'apparently'. For example, if you see dark clouds, you might say 雨が降るらしい. If you heard from a friend that a teacher is strict, you might say あの先生は厳しいらしい.
Unlike そうです (which you attach to the stem for appearance), らしい attaches to the plain form. It is also different from ようです, which is more formal and based on more direct evidence. らしい is common in everyday conversation and is neutral in politeness, so you can use it with friends or in casual settings.
