Frequently Asked Questions
Why is it 'diez' but then 'dieciséis' for sixteen?
Great question! For numbers 16 through 19, Spanish combines words. 'Dieciséis' is a smooshed-together version of 'diez y seis' (ten and six). The 'z' in 'diez' changes to a 'c' to keep the right sound.
Is 'diez' ever plural, like 'dieces'?
Almost never when you're just counting. You'd say 'diez coches' (ten cars), not 'dieces'. You might only see 'dieces' if you're talking about multiple number 10s, like 'Saqué dos dieces en mis exámenes' ('I got two tens on my exams'), but this is less common.
