Hey if you click the link button　on　the　link　to　the　word　you　can　search　for　sentences,　they　have　a　lot　of　sentences　for that word

Or you can search rashii #sentences in the search bar I think

Actually it looks like you need to type it in actual Japanese to search for sentences so you'd have to search like this
「らしい #Sentences」

Ok, this is how you search for it 「らしい #sentences」 You can't capitalize that S.

rashi is tricky. Usually taught with mitai and you (da). All of which can be similar.
The best way I've found to think of it is the meaning "typical of" whatever noun it follows.
basically conjugates like any adjective
