好像【hǎoxiàng】

好像 says something seems to be so. It goes after the subject or at the start, and the speaker isn't certain.

With a memory or a guess about yourself, it softens to "I think".

"As if"

Followed by 一样 or 似的, 好像 compares: things look as if something were true, though they aren't.

Before a noun, it means "be like", and 一样 is optional.

Where 不 goes

The negative goes after 好像, on the thing that seems to be so.

• × 他不好像在家 → 他好像不在家

似乎 is the written word for "it seems"; 像 alone is "resemble" and doesn't carry the uncertainty.
