Catalan ordinal numbers
 <  2n 3r 4t  > 
    Cardinal : tres
    Ordinal : tercer
    Multiplier : triple


From Latin tertiarius.



tercer (feminine tercera, masculine plural tercers, feminine plural terceres)

  1. (ordinal) third

Usage notes[edit]

When tercer is the ordinal number of a century or of a regnal name of a monarch or pope, it is written using Roman numerals following the noun. Thus Joan Tercer is written Joan III.

For most fractional numbers, the ordinal number is used to indicate the denominator of the fraction. Tercer and its forms are seldom used to indicate fractional thirds. Instead, terç is used. Exceptions to this rule include mig (half), terç (third), quarter (quarter), milionèsim (millionth), bilionèsim (billionth), ....

The feminine form of the ordinal is usually used as the collective noun for a set of like objects of that size. Exceptions to the usual rule include parell (set of 2), qüern (set of 4), centenar (set of 100), grossa (set of 144), miler (set of 1000), and milenar (1000).


tercer m (plural tercers, feminine tercera)

  1. mediator ; a third party who negotiates between two other parties in a dispute
  2. (obsolete) tierce; unit of liquid measure


Alternative forms[edit]




  1. (transitive) to plough a third time


This verb is part of a group of -er verbs for which ‘c’ is softened to a ‘ç’ before the vowels ‘a’ and ‘o’.



tercer m (apocopate, standard form tercero)

  1. (before the noun) Apocopic form of tercero (third).
    El tercer hijo.
    The third child.

Usage notes[edit]

  • The form tercer is only used before and within the noun phrase of a modified masculine singular noun. In other positions, the standard form tercero is used instead.
