Explanation:
In Spanish, the city and country of origin are proper nouns, so they start with a capital letter. Nationalities are adjectives, so they change according to the gender and number (singular and plural) of the subject. For a singular male, the letter -o should be placed at the end of the nationality, or an -a for a singular feminine noun. Some nationalities are neuter, they have a single form for both men or women, like canadiense.
