Questions & Answers about היא נראית עייפה, אבל היא נשמעת שמחה עכשיו.
Because the subject is היא = she, so the words that describe her are feminine singular.
You can see that in:
- נראית = looks/seems (feminine singular)
- עייפה = tired (feminine singular)
- נשמעת = sounds (feminine singular)
- שמחה = happy (feminine singular)
If the subject were הוא (he), you would usually get:
- הוא נראה עייף, אבל הוא נשמע שמח עכשיו.
- נראית literally means is seen / appears / looks
- נשמעת literally means is heard / sounds
In natural English:
- היא נראית עייפה = She looks tired
- היא נשמעת שמחה = She sounds happy
So Hebrew uses these verbs much like English uses looks and sounds.
