Confusion around the "With" skill
My problem is that I can't really tell the difference between Adjective Formation and the Instrumental Case (they are introduced in the "With or without" skill).
For me, it's quite ambiguous because their function seems to be the same and they only differ in their suffix. If you translate them to English, both turn into "with". There isn't anything in Hungarian (my native language) either, that could tell them apart when translated.
My only tip is that you use Adjective Formation with objects and not living things, and you use the Instrumental Case for people and living things. However, I haven't seen this confirmed anywhere yet.
Could someone please explain to me the difference, and when to use which?
I appreciate any help you can provide.
Are you talking about "li" and "le"?
X'li Y means "Y contains X". "Y has X in it". They're not separable.
X'le Y means "Y and X side by side". In most cases, you can replace this "'le" with "ve" (and).
If you go to a café and ask: "Sütlü kahve," they will serve you coffee with milk inside: milked coffee.
If, on the other hand, you ask: "Sütle kahve," they will bring a cup of coffee and a cup of milk.
In Hungarian, our -li is translated with the suffix -s, while our -le is simply "és": sütle kahve = tej és kávé ; sütlü kahve = tejeskávé.
Both -li and -le can be used for living things.
So, if in Hungarian you can add "-(e)s", use "-li" ; if you can use "és" or "-vel", use "-le"
