प्रत्यय जड़ के प्रत्यय होते हैं और अक्सर किसी शब्द के अर्थ और कार्य को बदल देते हैं। सामान्य तौर पर, एक प्रत्यय एक प्रकार के शब्द को इंगित करता है, जैसे संज्ञा, विशेषण, आदि। उदाहरण प्रत्यय। शब्दावली उदाहरण सनसनी, आंदोलन, आलोचना, सफल, स्थापित, सिंक्रनाइज़, आदि।

Just to add a couple of remarks to Konrad509's answer.
Yes, one of the right answers is:
わたしはじゅうさいです。
[watashi ha juu-sai desu.]
In kanji it looks like this:
私は十歳です。
or
私は十才です。
If you wanted to customize your sentence a little bit then I would suggest changing the first person pronoun to something else. Therefore, if you're a girl, you might to use あたし [atashi] instead of わたし (私) [watashi]; if you're a teenage boy who wants to sound cool on the other hand, you might want to use おれ (俺) [ore].
Also you might want to add よ [yo] at the end of the whole sentence to sound more amiably.
I hope that it clears everything up for you. If you had more questions, you can just write to me personally ;)
Cheers!
