"I am a dove."
The letter י (yod) is Y
The letter ן (vav) can be V or O, here it is O
The letter נ (nun) is N
The letter ה (hei) is H but some people don't pronounce it
This gives you יונה, yonah, which can mean "dove" or the first name Jonah.
(Even though you probably made this comment a long time ago [can't see dates on the app], learners may still find this helpful.)
There are three Hebrew letters that are basically vertical lines, but they differ in size. I like to think of them as the "Three Bears". Yod, the smallest vertical letter (that looks more like an apostrophe) is the "Baby Bear". Then Vav, the medium-sized vertical line, is the "Mama Bear", and the final form of Nun is a large vertical line that's the "Papa Bear".
Yod is basically the Hebrew letter Y, while Vav is the letter V (but can also be used as an "o" or "u" vowel. The final form of Nun simply appears at the end of a word (you would otherwise use the standard Nun). Nun is one of five letters that has a final form as well as its regular form.
Don't ask me which letter is Goldilocks, though. :-)
