Questions & Answers about אני יכולה לקרוא בלי שמאמץ העיניים מפריע לי.
Because the speaker is female.
In Hebrew, יכול / יכולה agrees with the subject:
- אני יכול = I can (said by a male)
- אני יכולה = I can (said by a female)
So in this sentence, אני יכולה לקרוא tells you the speaker is feminine.
Hebrew often expresses can / be able to with the adjective-like form יכול / יכולה plus an infinitive.
So:
- אני יכולה לקרוא = I can read
- literally, it is something like I am able to read
This is the normal way to say can in present tense Hebrew.
