➤ Basic usage rule for “uno” with nouns:
When uno comes before a masculine noun, it usually changes to un (because Spanish adjectives and determiners agree with the gender of the noun). For masculine nouns use un libro (one book). For feminine nouns use una mesa (one table).

➤ Gender agreement example:
Use una before feminine nouns: una silla (one chair). Spanish number words do not change gender except for this uno → un/una agreement rule.

➤ Counting and everyday use:
Use these numbers for counting objects:
Siete chairs would be siete sillas.
Dos cats would be dos gatos.

➤ Telling age:
To say someone’s age use tener (to have) + number + años: Él tiene ocho años means “He is eight years old.”

➤ Telling time (hours):
Spanish uses the plural form of “to be” for most hours: Son las tres means “It’s three o’clock.” For one o’clock alone Spanish uses Es la una.

➤ Phone numbers and digits:
Read each digit separately: when saying a phone number, say tres cero cinco… etc.

➤ Prices and quantities:
Use number words before nouns: Cuesta cinco euros means “It costs five euros,” and Tengo diez libros means “I have ten books.”

➤ Pronunciation tips:
Spanish pronunciation for numbers is generally consistent: most letters are pronounced clearly. Dos and tres end with a clear s. Seis has the diphthong ei, sounding similar to English says. Nueve begins with a light nw sound.

---

➤ Common mistakes to avoid:
Make sure to match uno with un/una when it comes before nouns. Practice the ei sound in seis and nue in nueve to sound natural.
