The numbers 21, 22, and 23 follow a similar pattern.
The number 21 is called veintiuno. This number is unique because when it's paired with a masculine noun like años, it changes to veintiún, with an accent mark on the letter u.
The number 22 is called veintidós, with an accent mark on the letter o.
The number 23 is called veintitrés, with an accent mark on the letter e.
These numbers are a combination of veinti and the corresponding number (uno for 1, and dos for 2, and tres for 3).
Listen to their pronunciations and practice repeating them until you feel more comfortable with their sounds.
