"They are tall girls."
Translation:Ona jsou vysoká děvčata.
I put something similar, and it was accepted. Anyway, my question is different: In "Ony jsou vysoké dívky" (what I put), I made mental connections with "OnY" & "divkY" and "jsou vysokÉ" as plural for a feminine noun--with "jsou" & "vysoké" grouped separately from "Ony" & "dívky" for some reason.
However, in the sentence, "Ona jsou vysoká děvčata", I noticed that the "vysoká" is conjucted with an "á" instead of an "é". Is this because "děvčata" is considered neutral rather than feminine, even though it is also referring to a group of girls? If so, why?
P.S. (I initially confused the "á" for an "a" in "vysokÁ", thinking it was conjucted in the singular feminine form with the plural group "Ony" & "vysoké", but think I resolved my confusion when I noticed the letter was the plural neutral "á". Hope I haven't confused you now.)
Yes, děvče is grammatically neuter, even though it means "girl." The plural, děvčata, also is neuter (as is true for most nouns; some "change gender" from singular to plural, but never mind that for now).

We do not accept velký instead of vysoký here although in common speech we would often use velký while having the height in mind. We are probably not completely consistent here. For example, we do accept velký in "That man is tall.". Perhaps we will unify it, one way (adding) or the other way (removing).
If you were to use "oni", there would have to be at least one male in the group. Here you have only girls (děvčata is a neuter noun - Ona jsou děvčata.; or you can use holky/dívky which are both feminine nouns and then use the feminine personal pronoun in plural - Ony jsou holky/dívky.)
Actually, after doing the exercises a couple more times, I'm thinking "to" is like another stand-in for "they," whereas "ty" would be "those." Like "To jsou vysoke holky" = "they are tall girls" vs. "ty holky jsou vysoke" = "those girls are tall."
I don't know if that's right, but that's the pattern I noticed after practicing a few more times.
"Ty holky" is gramatically correct, generally. There is a special rule that when stating plurals with the "to be" verb that you always use "to", regardless of the gender. For example, "To jsou pomeranče" (those are oranges) or "To byli jeho kamarádi" (those where his friends).
You have to say "Ona jsou vysoká děvčata." because the adjective develops the noun, not the pronoun. It has to stick to it closely (and precede the noun, because it also agrees with the noun in grammatical categories). If there were more words in a sentence and adjectives describing different things, it would be even more obvious that they have to form inseparable units, so you'd know which adjective belongs to which noun.
