IOL 2006 Problem #2 Catalan
The plural of Catalan nouns is usually formed by adding the ending -s. But if the noun ends in one of the letters s, x or ç, more complex rules apply.

Here are the singular and the plural forms of some Catalan nouns (in simplified spelling) and their English translations. Some forms are missing.

(a) Fill the gaps. Explain your solution.

(b) The marks ` and ´ indicate the stress in certain Catalan words. Find out when they are used.

(c) Which syllable is stressed in those words where there is no ` or ´ mark?
