What is 45 in Spanish?: The Basics

In Spanish, cardinal numbers are used to count things or express quantities, while ordinal numbers are used to indicate the position or order of things. The Spanish ordinal form of 45 is "cuarenta y cinco" (IPA: /kwaˌɾenta i ˈsinko/). Here is how you can break it down:

  • “Cuarenta”: This means "forty" and is pronounced as /kwa.ɾen.ta/ (IPA).
  • “Y”: This means "and" and is pronounced as /i/ (IPA).
  • “Cinco”: This means "five" and is pronounced as /sinko/ (IPA).

Now, let us explore the ordinal form: “cuadragésimo quinto” (IPA: /kwadɾaˌxesimo ˈkinto/). To break it down:

  • "Cuadragésimo" means "fortieth" and is pronounced as /kwadɾaˌxesimo/ (IPA).
  • "Quinto" means "fifth" and is pronounced as /ˈkinto/ (IPA).

As you can see, Spanish cardinal numbers are relatively straightforward, while ordinal numbers require more complex vocabulary. In general, you can form ordinal numbers by using the suffix "-avo" or "-ésimo" and mixing it with the cardinal number, depending on the gender and number of the noun. Nonetheless, in this case it is needed to do something more than adding a suffix. As a matter of fact, “cuarenta y cinco” (45) becomes “cuadragésimo quinto” (45th) when "-dragésimo" is added to the first syllable of “cuarenta” (“cua") and it is used the cardinal form of “cinco”: quinto.
