Numerals — cardinal, ordinal 1–10, agreement, expression of time and date — WJEC A-Level Spanish

This topic covers the use of cardinal numbers (1–10) and ordinal numbers (1st–10th) in Spanish, including their correct agreement with nouns and their application in expressing time and dates. Mastering numerals is essential for everyday communication, from telling the time to discussing dates, prices, and quantities. In the WJEC A-Level exam, you will be expected to use numerals accurately in both written and spoken contexts, often within broader tasks such as describing routines or making arrangements.

Cardinal numbers (e.g., uno, dos, tres) are straightforward but require attention to gender agreement when used before masculine nouns (e.g., un libro, veintiún años). Ordinal numbers (e.g., primero, segundo) must agree in gender and number with the noun they modify (e.g., la primera clase, los segundos pisos). Additionally, the expression of time uses specific structures (e.g., es la una, son las dos) and dates require the definite article and the preposition 'de' (e.g., el primero de enero). Understanding these patterns is crucial for achieving high marks in accuracy-focused exam tasks.

This topic builds on foundational vocabulary and grammar, such as noun gender and basic verb conjugations. It also connects to other areas of the curriculum, including daily routine, travel, and cultural topics like festivals and historical dates. By mastering numerals, you will improve your fluency and precision, enabling you to handle a wider range of real-life and exam scenarios with confidence.

• →Cardinal numbers 1–10: uno, dos, tres, cuatro, cinco, seis, siete, ocho, nueve, diez. Note that 'uno' becomes 'un' before masculine nouns (e.g., un libro) and 'una' before feminine nouns (e.g., una casa).
• →Ordinal numbers 1st–10th: primero, segundo, tercero, cuarto, quinto, sexto, séptimo, octavo, noveno, décimo. They agree in gender and number (e.g., la primera semana, los primeros días). 'Primero' and 'tercero' drop the final -o before masculine singular nouns (e.g., el primer día, el tercer piso).
• →Telling the time: Use 'es la una' for 1:00 and 'son las' for all other hours. Minutes are expressed with 'y' (past) or 'menos' (to), e.g., son las dos y cinco, son las tres menos cuarto. For 12:00, use 'es mediodía' or 'es medianoche'.
• →Expressing dates: Use 'el' + cardinal number (except for the 1st, which uses 'primero') + 'de' + month, e.g., el cinco de mayo, el primero de enero. Years are expressed as cardinal numbers (e.g., mil novecientos noventa y nueve).
• →Agreement: Ordinal numbers must match the noun in gender and number (e.g., la segunda oportunidad, los octavos de final). Cardinal numbers are invariable except for 'uno' and compounds like 'veintiuno' (which become 'veintiún' before masculine nouns).

• Correct use of definite articles (el, la, los, las)
• Correct use of indefinite articles (un, una, unos, unas)
• Correct application of 'el' before feminine nouns beginning with a stressed 'a' (e.g., el agua, el alma)
• Correct use of 'lo + adjective' to express abstract concepts (e.g., lo importante, lo bueno)

• 💡Remember that 'el agua' is feminine despite the masculine article; adjectives modifying it must remain feminine (e.g., el agua fría)
• 💡Use 'lo + adjective' to add sophistication to your writing when discussing abstract concepts or opinions
• 💡Check for stressed 'a' at the start of feminine nouns to avoid the common 'la' error
• 💡In written tasks, always double-check the agreement of ordinal numbers with the noun they modify. A common mistake is to leave them in the masculine singular form regardless of context. Practice writing sentences like 'La tercera clase es difícil' to reinforce agreement.
• 💡When expressing dates, remember that the first day of the month uses 'primero' (e.g., el primero de enero), but all other days use cardinal numbers (e.g., el dos de febrero). This is a frequent exam pitfall.
• 💡For time, be precise with the use of 'y' and 'menos'. In listening and reading exams, pay attention to whether the time is given in the 12-hour or 24-hour clock. In speaking, practice saying times naturally, including phrases like 'y cuarto' and 'y media'.

• Using 'la' instead of 'el' before feminine nouns starting with a stressed 'a'
• Confusing 'lo' with masculine articles (el/un) when referring to abstract ideas
• Incorrect agreement of articles with nouns
• Using 'uno' instead of 'un' before masculine nouns: For example, saying 'uno libro' instead of 'un libro'. Remember that 'uno' shortens to 'un' before masculine singular nouns, just like 'bueno' becomes 'buen'.
• Forgetting that ordinal numbers must agree: For instance, writing 'el primero capítulo' instead of 'el primer capítulo'. Ordinals agree in gender and number, and 'primero' and 'tercero' drop the -o before masculine singular nouns.
• Confusing time expressions: Saying 'son las una' instead of 'es la una'. Use 'es' only for 1:00 (and 1:00 AM/PM), and 'son' for all other hours. Also, remember that 'y' is used for minutes past and 'menos' for minutes to the hour.
