"The goat eats food."
Translation:Koza žere žrádlo.
Short and simple: "Žrát/žrádlo" apply to animals while "jíst/jídlo" apply to people.
A little bit more thorough answer: In common speech it's ok to use "jíst" about your beloved pets (Můj pes jí granule), however, it sounds weird with "koza". You probably wouldn't say "jídlo" with animals unless you're feeding your dog with human food. But "dog food" is always "psí žrádlo".
On the other hand you can use "žrát" for people, but it's very informal speech. More than plain "žrát" you can encounter "sežrat něco" - "Všechno jsem to sežral = I ate it all" or "nažrat se". The Czech dictionary I use translates "nažrat se" as "wolf something down" :-) https://slovnik.seznam.cz/cz-en/?q=na%C5%BErat%20se
"Žrádlo" can be used for human food as well but again, it'w very colloquial and it is connected with negative context - you don't like the food or something in that manner.
Koza žere žrádlo. is the most natural.
Žrát and žrádlo are used mainly when referring to animals. (for example psí žrádlo means 'dog food.' Jídlo on the other hand is like 'food for human consumption.')
Koza jí jídlo is a bit strange. You usually don't use jíst when referring to animals. Using jídlo implies that the goat is eating something that is intended for human consumption.
Markéta žere žrádlo. is very rude, don't use it. Using žrát when referring to humans implies that their manner of eating is like that of an animal.
Markéta jí jídlo. is perfectly acceptable.
Summary: žrát and žrádlo - animals; jíst and jídlo - humans; žrát + 'humans' = big NO NO
Hope it helps and happy learning! :)
If it's not specified, the default gender for a goat is feminine in Czech, hence goat=koza. It's the same with all animals - e.g. a cat is automatically kočka (female, a ❤❤❤❤❤ cat), unless you specify tom-cat, then it's kocour (male). A dog is male in Czech by default - pes, unless you want to go out of the way and stress that the dog is female (a ❤❤❤❤❤), then you'd use the word fena in Czech instead.
This is the same in other gendered languages, for example in French it's le chat, le chien, la chèvre (female goat) by default, in German die Katze, der Hund, die Ziege (also female goat) by default.
Yes, surely. And it is.
