adverbial N3 common politewritten

やはり — as expected / after all

やはり

Meaning

as expected / sure enough / after all — reality matches what one anticipated, or a return to a prior conclusion

Confirms an expectation ('just as I thought'), or signals a settled second thought ('on reflection, after all').

やはり彼かれが一番いちばん強つよかった。

As expected, he was the strongest.

やっぱり — The everyday conversational form; やっぱ is even more casual.

色々いろいろ見みたが、やはりこれが一番いちばんいい。

I looked at lots of options, but this is the best after all.

やはり来こなかったか。

So he didn't come after all, huh.

Jengo shows やはり the way you actually meet it: inside real Japanese sentences, so it sticks instead of staying an abstract rule.
