I think this is meant to be a clause, but a complete sentence - "The book that is big and heavy is on the table" but it's true, this item is very awkward.
I've reported all such entries, as frankly they are a bad way to teach these things as they are not inherently obvious as to which they should be. One capitol letter and it's a sentence in and of itself, and thus they are easy to overlook. They should turn these into complete sentences to teach the grammatical item in question.
I put “that which is big and heavy” and it was marked wrong. What am I missing? I thought ami was “that which is...” or “the thing that is” and Aki is the person which is or person that is
Well, you're not far off. But ami and aki are just the "which/what/who" part. It's just a sentence fragment here.
For "that which is big and heavy" you'd say "az, ami nagy és nehéz". Az being "that".
Using large (rather than big) should be accepted as an accurate translation no?
Is 'ami' used when 'that' isn't specified? Eg. 'that' on its own would be 'ami' but 'that [object]' would be 'az a(z) [object]'?
Ami is a relative pronoun which starts a relative clause. This task here is just a fragment of a sentence, like "Tartom, ami nagy és nehéz." - "I hold (the thing) that is big and heavy." Ami is related to mi - what.
A full sentence of "That (thing) is big and heavy." would translate to "Az nagy és nehéz". On the other hand, "Az a nagy és néhez" would translate to "That big and heavy thing" or "That is the big and heavy thing."
The lack of a verb makes these things a bit ... nehéz to figure out. :´)
Yeah, I get it now, I'm a bit further ahead than where I was when I posted that so I know what it's used for. Thanks!
Ami is related to the question word mi - what. As such it is a relative pronoun that refers to a general object and can also be translated as "what" or "that". A daru mindent emel, ami nagy és nehéz - The crane lifts everything that is big and heavy.
Aki is related to the question word ki - who. It's a relative pronoun that refers to people, usually also translated as "who". Azt a gyereket tartom, aki nagy és nehéz. - I am carrying the child who is big and heavy.
