Ordinal Numbers
Ordinal numbers are first, second, third, etc.
primero - first
segundo - second
tercero - third
cuarto - fourth
quinto - fifth
sexto - sixth
séptimo - seventh
octavo - eighth
noveno - ninth
décimo - tenth
Beyond tenth cardinal numbers (one, two, three etc.) should be used instead of ordinal numbers to simplify matters: once - eleventh, doce - twelfth etc.
However, there is a more complicated method of expressing the ordinal number system, but we don’t advise you to use it. For example, eleventh is undécimo, twelfth is dudécimo. For numbers 13-19 put décimo in front of the ordinal numbers 3-9: decimotercero (13th) or decimocuarto (14th) etc.
Some of the the ordinal numbers are:
vigésimo - twentieth
trigísimo - thirtieth
cuadragésimo - fortieth
quincuagésimo - fiftieth
sexagésimo - sixtieth
septuagésimo - seventieth
octogésimo - eightieth
nonagésimo - ninetieth
centésimo - hundredth
