"È meno chiaro come parole seguano una regola simile."

Translation: It is less clear how words follow such a rule.

I knew that I have to use the subjunctive after every 'che', but I've seen a lot of sentences lately that require the subjunctive even without the 'che'...could somebody enlighten me please?

[GeniusJack]

The subjunctive is also used to express doubt, fear, joy, hope or some other emotions.

[Realejo]

Thank you for answering question (twice-sorry!)

[GeniusJack]

You're welcome. It's fun to actually be able to help someone!

[Realejo]

Oh I'm sure you are a great help for a lot of people here! (Especially if you know a lot about Italian grammar..not exactly my forte.)

..Aand there's a 'my' missing in my first reply.

[GeniusJack]

I haven't really helped very many people, perhaps I should do more. Thanks anyways!

Why is there "such a rule" as Duo's intended translation instead of "a similar rule" (marked correct) ?

[Blomeley]

simile also means "such". Such and similar are such similar words anyway....
