Questions & Answers about Mi padre tiene treinta años.
Why does the sentence use tiene (has) instead of a word for 'is'?
Is there a trick to remembering the word treinta (thirty)?
Yes! Notice how treinta starts with tre-, just like the word tres (three). Also, most of the 'tens' in Spanish end in -enta, like cuarenta (forty) and cincuenta (fifty). Treinta follows a very similar pattern with its -inta ending.
How important is the squiggly line over the 'n' in años?
It is extremely important! That letter is ñ, and it makes a sound like the 'ny' in the English word 'canyon'. If you forget it and write an ordinary 'n', the word changes to a medical anatomy term that is very impolite to use by accident. Always double-check your spelling for años!
