Ordinal Numbers in Spanish

Introduction to Ordinal Numbers

Ordinal numbers in Spanish, known as “números ordinales,” indicate the position or order of objects, people, or concepts in a sequence. Unlike cardinal numbers, which quantify items, ordinal numbers establish a hierarchy or sequence.

Importance of Ordinal Numbers

1. Indicating Order: Ordinal numbers are crucial for showing the sequence or order of items, such as in a list or a competition.
2. Describing Floors in Buildings: They are commonly used to talk about floors in a building (e.g., “first floor” – “primer piso”).
3. Events and Anniversaries: Ordinal numbers are used to mark significant events or anniversaries, such as a country’s independence day (“second anniversary” – “segundo aniversario”) or a wedding anniversary (“25th anniversary” – “vigésimo quinto aniversario”).
4. Academic and Professional Rankings: They play a role in academic and professional settings, such as class rankings or stages in a process (“third stage” – “tercera etapa”).
5. Narrative and Storytelling: Ordinal numbers help in structuring narratives, like chapters in a book (“Chapter 1” – “Capítulo primero”) or sequences in a story (“second part” – “segunda parte”).

Basic Ordinal Numbers: 1st-10th

• 1st: First (Primero/a)
• 2nd: Second (Segundo/a)
• 3rd: Third (Tercero/a)
• 4th: Fourth (Cuarto/a)
• 5th: Fifth (Quinto/a)
• 6th: Sixth (Sexto/a)
• 7th: Seventh (Séptimo/a)
• 8th: Eighth (Octavo/a)
• 9th: Ninth (Noveno/a)
• 10th: Tenth (Décimo/a)

Note: The ordinal numbers agree in gender with the nouns they modify (e.g., “primer piso” for “first floor,” “segunda etapa” for “second stage”).
