What's the difference between these 2 sentences and why is "a" necessary? It's supposedly wrong without it.

 

[jazyk]

Yes, it's wrong without it.

Genitiv

This particle you are asking about plays the similar role as the English 'of' does in the following example: The reaction of my lungs was nasty. (whose reaction is that?)

 

[盲人瞎馬]

Yes, it's wrong without it.

Genitiv

Thanks.

 

[irinet]

Without 'a' it would be similar to the ' lung reaction'😄 but a new word came along, which is the modifier - imune'.

 

[farscape]

You could use this construction with a different meaning though : "o reacție imună plămânilor" 😊

Now, see the difference with the noun 'reacția' vs 'o reacție'. That's a linguistic trap indeed.
