Questions & Answers about A felhasználó megnézi az e-mailt.
Both a and az mean the.
The choice depends on the sound that follows:
- a before a consonant sound: a felhasználó
- az before a vowel sound: az e-mailt
So this is similar to English a / an, except in Hungarian it happens with the, not with the indefinite article.
The -t is the accusative ending, which marks the direct object of the verb.
Here, the email is the thing being looked at / checked, so Hungarian marks it:
- az e-mail = the email
- az e-mailt = the email as a direct object
English usually shows this by word order, but Hungarian often marks objects directly with a suffix.
