To make a verb negative, the particles 'ne' and 'pas' are placed around the verb. For example:
'Je ne vais pas en ville': 'I’m not going into town'
Nothing can come between the verb and 'pas' except a subject pronoun when the verb is in the interrogative form. For example,
'Ne regardez-vous pas le match de football?': 'Aren’t you watching the football match?'
Remember that 'ne' will be shortened to 'n’ before a vowel.
