"The boy doesn't want water."
Translation:הילד לא רוצֶה מים.
Mem sofit is ם. Likewise, you have the other sofit characters. ךףץן. Aside for Mem Sofit, all the tailed characters. Sofit, I believe, means 'final'.
Just gotta see if I understand the letter ו and י correctly. ו is pronounced "v" at the start of a word, but becomes "o" or "u" between certain/all letters? And י is always "j", but with the sound of a vowel after it, like "jo", "ju", "je"? I'm a bit confused by the vowels that's put inbetween.
The letter י can have the consonant sound of y as well as the long e sound. When it is a consonant, it can be followed by any vowel sound (as far as I know).
