I'm not 100 % sure how you mean, but there are four syllables in pojken äter. I'll list them with English approximations.
- poj - "poy"
- ken - "ken"
- ä - "eh"
- ter - "ter"
In practice, however, a word that ends in a consonant will often kind of merge with the next word, if that starts with a vowel. So you'll still have four syllables but for a non-native they may be a bit tricky to discern.
It's the same in English as well, but you never think about the process in your own language until you start explaining it to somebody else. :)
Hope that helps.
How do you know when a "the" exists in a swedish word? Is it the ending? This one counts "the fruit" but not "fruit" which of course can in contexts make a huge dofference. How does one know fpr example, whether the swedish is saying "he doesnt like fruit" or "he doesnt like THE fruit"
