Il faut éviter : indefinite, demonstrative and interrogative adjectives

'Même(s)', 'autre(s)', and 'quelque(s)', meaning 'same', 'other' and 'some', agree in number with the noun. 'Tout le' meaning 'whole' or 'all' agrees in number and gender. 'Chaque' (each) and 'plusieurs' (several) do not change. [c] is soft before e, i and y or if it has a cedilla [ç]: merci, ça va. Before all other letters, [c] is a hard sound. Use demonstrative adjectives 'ce, cet, cette, ces' to mean 'this/that/those'; they often answer the question 'which?' Use interrogative adjectives 'quel, quelle, quels, quelles' to ask 'which?'
